21 Best Space Anime, Ranked

Space anime has never been about starships and laser fire alone. It is about what the silence of the void does to a person once there is nowhere left to run. Some of the best space anime use that emptiness as a mirror, and that is the lens I ranked this whole list through.

Below you will find the best space anime across every mood, from gritty orbital-debris realism to psychedelic galaxy-ending battles. I sorted them by how much they still get talked about, so scroll to the bottom for my number one pick.

Before we launch, here is how I tagged each show in the wider world of anime.

How to Read This List

Every entry gets a “Navigation Specs” card with a vibe tier, so you can pick a show by the kind of trip you want. The four tiers I used:

• Cold War: fleet-level strategy, diplomacy, and the crushing weight of politics in space.
• Survivalist: claustrophobic and tense, where a leaking seal is a death sentence.
• Wanderlust: space as a road trip, built around the people you meet along the way.
• Supernatural Frontier: the mystical, the weird, and the reality-bending edge of the galaxy.

Each card also lists a vessel type and an “isolation level” from 1 to 5, rating how much the show leans on loneliness versus crew connection. Now let us set a course.

Blue Comet SPT Layzner

This 1985 mecha war story follows Eiji, a half-human pilot caught between Earth and the invading Grados. He stumbles onto a powerful machine called the Layzner and gets dragged straight into an interstellar conflict.

The first half is tense Mars-and-space drama. The second half jumps years ahead into an occupied Earth, which was a bold swing for the era.

• A Ryosuke Takahashi war story, so expect real stakes over easy heroics.
• Strong theme of trust between old enemies.
• Very much an old space anime, but the character work holds up.

Why it stuck with me: the tonal gear-shift halfway through is the kind of risk modern shows rarely take.

Banner of the Stars

The direct sequel to Crest of the Stars picks up with Jinto and Lafiel now serving in the Abh military during open war. The politics widen, the fleet battles get bigger, and their bond keeps deepening under pressure.

It rewards you for having watched the first series. Skip ahead and half the weight is lost.

• Tactical space combat with actual strategy behind it.
• Quiet character growth between the battles.
• A worthy follow-up rather than a cash-in.

Where I land: this is comfort-food space opera anime for people who already love the universe.

Infinite Ryvius

Set in 2225, this one strands nearly 500 students on a stolen ship after a disaster kills the adults. What follows is less about aliens and more about how quickly a society of teenagers turns on itself.

Think Lord of the Flies in orbit. The tension comes from politics inside the hull, not enemies outside it.

• Sharp psychological pressure that builds slowly.
• A big cast, each cracking in a different way.
• One of the tensest space survival anime out there.

My verdict: underseen and underrated, especially if you like your sci-fi bleak and human.

Stellvia of the Universe

Shima Katase enrolls at a space station academy to train as a pilot in a future still healing from a cosmic shockwave. A second wave is coming, and humanity has one shot to prepare.

It is a coming-of-age story first and a disaster story second. The friendships carry it.

• Warm, hopeful tone throughout.
• Focus on teamwork and self-doubt over spectacle.
• Easy watch for all ages.

My call: a gentle entry point if the heavier war stories feel like too much.

Crest of the Stars

Jinto, a young human noble, ends up traveling with Lafiel, a princess of the star-faring Abh Empire, as war erupts around them. It is a slow-burn romance wrapped in dense worldbuilding.

The Abh get their own invented language and culture, which sells the scale. Patience pays off here.

• Two leads with real, understated chemistry.
• Political intrigue that truly drives the plot.
• Foundational for later space opera anime.

What hooks me: the quiet moments between two people from opposite worlds land harder than the battles.

Heroic Age

Heroic Age wraps a space opera around a myth-flavored setup of warring tribes and a chosen champion. A boy named Age carries a terrifying power that could reshape the fate of humanity.

The scale is huge and the battles turn apocalyptic. It leans hard into destiny and prophecy.

• Massive, planet-cracking fight sequences.
• A classic hero-versus-fate structure.
• Rich enough worldbuilding to reward a rewatch.

Straight up: if you want cosmic power fantasy with mythic weight, this delivers.

Bodacious Space Pirates

Marika is a normal high schooler until she inherits her late father’s legal pirate ship and its crew. Suddenly she is balancing homework with running the Bentenmaru.

The word “pirate” here means licensed privateer, so it is more heist and adventure than raiding. The tone stays bright and fun.

• A likable lead who grows into leadership.
• Clever, low-stakes capers across the galaxy.
• An easygoing take on the space pirate anime idea.

My two cents: it is comfort viewing with a surprisingly competent heroine at the wheel.

Terra Formars

Centuries of terraforming Mars with algae and cockroaches goes horribly wrong. The roaches evolve into towering humanoid killers, and a crew of gene-modified humans has to clear them out.

It is brutal, pulpy, and not shy about body horror. The premise alone is worth the price of entry.

• Insane concept executed with real intensity.
• Combat built around bizarre bug-based powers.
• A darker corner of space colonization anime.

My honest read: the plot is messy, but few shows commit to a wild idea this hard.

Planetes

Planetes follows the people who collect space debris in near-future orbit, and it is the most grounded show on this list. A loose bolt at orbital speed is a lethal weapon here.

Under the workplace drama sits a real story about ambition and what it costs. The physics feels researched.

• Believable, lived-in vision of working in space.
• A slow-burn romance that earns its ending.
• One of the smartest space exploration anime ever made.

Why I rate it: it makes garbage collection in orbit feel like the most human job in the galaxy.

Captain Harlock

Harlock is the original brooding space pirate, sailing the Arcadia against a lazy, corrupt Earth government. He fights for freedom while everyone below is too comfortable to notice the threat.

Leiji Matsumoto’s style is unmistakable, all long silhouettes and star-swept romance. It set the template for a lot of what came after.

• An iconic, principled antihero.
• A gorgeous, skull-flagged flagship.
• Essential viewing among space pirate stories.

My take: Harlock is cool in a way that never feels dated, and that is rare.

Space Brothers

Two brothers made a childhood promise to reach space. Years later the younger one is already an astronaut, and the older one is only just starting to chase the dream.

It is grounded and patient, closer to a real astronaut’s road than a laser battle. The training and testing feel authentic.

• A warm, motivating story about not giving up.
• Loads of real spaceflight detail.
• Emotional without ever feeling cheap.

The pull for me: the slow climb toward a lifelong goal is more gripping than most action shows.

Astra Lost in Space

A school camping trip goes sideways when nine kids are flung thousands of light years from home. Their only way back is ship-hopping across strange planets on a small vessel called the Astra.

What starts as a survival story turns into a tight mystery with a real payoff. The pacing is excellent for a single cour.

• Likable cast with quick, natural chemistry.
• A central space anime mystery that sticks the landing.
• A clean, modern space survival anime.

Where I stand: it is one of the most satisfying self-contained sci-fi stories in years.

Space Dandy

Dandy is a carefree alien hunter cruising the galaxy with a rundown robot and a cat-like alien. Each episode is its own self-contained experiment, often ignoring what came before.

Some episodes are pure comedy, others go strange and beautiful. Different directors got to swing wild every week.

• Gorgeous, constantly shifting animation.
• Standalone space anime episodes you can drop into anywhere.
• A loose, playful outer space anime.

What I love: the sheer freedom of it, where any episode might be a masterpiece or a joke.

Outlaw Star

Gene Starwind and his crew end up piloting an advanced ship with grappler arms and a built-in navigator, chasing a legendary treasure. It blends gunslinging, magic, and hard sci-fi without blinking.

The ship duels, where vessels literally grab and brawl, still look like nothing else. It captures that late-90s adventure energy perfectly.

• A charming, bickering crew.
• Wildly inventive grappler-ship combat.
• A cult favorite space western anime.

Why it lands for me: it is pure fun, and the Outlaw Star itself is one of the coolest ships in the medium.

Knights of Sidonia

Humanity’s survivors live aboard a city-sized ship called Sidonia, fleeing an alien horror known as the Gauna. Young pilots strap into mecha to hold the line, and the losses are real.

The setting is bleak and lived-in, with resource scarcity baked into daily life. The dogfights in the void stay tense throughout.

• A convincing sense of a whole society under siege.
• High-stakes mecha combat with heavy casualties.
• Sleek, unnerving alien design.

My read: few shows make the vastness of space feel this hostile and lonely.

Space Battleship Yamato

Space Battleship Yamato sends a converted battleship on a desperate voyage to save a dying Earth, with a hard deadline ticking the whole way. It practically invented the modern space epic.

The crew, including the steady Yuki Mori, has to survive a running war against the Gamilas empire. The ship’s Wave Motion Gun became an instant legend.

• A foundational classic that shaped the genre.
• Real stakes and a countdown that never lets up.
• The blueprint many later shows quietly follow.

Where I land: almost every space anime after this owes it a debt, and it still holds up.

Legend of the Galactic Heroes

Legend of the Galactic Heroes pits two brilliant strategists against each other across a decades-long war between an empire and a democracy. Reinhard chases order through power, Yang defends a flawed republic he barely believes in.

The show cares as much about political philosophy as it does about fleet battles. At 110 episodes, it is a commitment that rewards every hour.

• Two of the best-written leads in all of anime.
• Fleet warfare on a truly epic scale.
• The gold standard for thoughtful space opera anime.

My verdict: nothing else in the genre balances big ideas and huge battles this well.

Macross Frontier

A colony fleet drifting toward a new home runs into a hostile alien swarm called the Vajra. The response mixes three things Macross always loves, which are dogfights, a love triangle, and pop music.

Two idol singers, Sheryl and Ranka, matter as much to the plot as any pilot. The transforming Valkyrie fighters remain a spectacle.

• Standout memorable characters on every side.
• Concerts and battles woven into one sequence.
• Some of the sharpest mecha action of its era.

What hooks me: only Macross would let a song turn the tide of a space battle and make it work.

Gundam Series

Since 1979, Gundam has used giant piloted mecha to tell hard stories about war, politics, and youth caught in the middle. Whole colonies live in space, and most of the fighting happens there too.

You can start almost anywhere, since many entries stand alone. The through-line is always the human cost of conflict.

• A franchise deep enough to explore for years.
• Iconic mecha and equally iconic tragedies.
• The backbone of space battle anime as a whole.

My call: no single show, but as a body of work it defines the genre.

Gurren Lagann

It opens underground with two kids and a tiny drill mecha, then keeps escalating until the battles are literally galaxy-sized. Few shows expand their scope this fearlessly.

The heart of it is momentum, willpower, and refusing to quit. By the finale, mecha are throwing galaxies like stones.

• An unmatched sense of escalating spectacle.
• Big emotional gut-punches along the way.
• Pure adrenaline once it hits space.

Why it stuck with me: the leap from a hole in the ground to the edge of the cosmos still gives me chills.

Cowboy Bebop

Cowboy Bebop follows a ragtag crew of bounty hunters drifting the solar system aboard the ship Bebop. Led by the laid-back Spike Spiegel, they chase easy money that never quite comes.

The real story is the past none of them can outrun. Its jazz score and retro-future look still feel effortlessly cool.

• A perfect fusion of noir, western, and sci-fi.
• One of the greatest soundtracks in the medium.
• The go-to recommendation and the best space anime for newcomers.

My take: it is my number one because it uses the void exactly the way this whole list is about, as a mirror for people who cannot run from themselves.

Your Turn to Set a Course

That is my ranking, from grounded orbital grunt work all the way up to Spike and the Bebop. The beauty of the genre is how differently each of these treats the same empty sky.

So where do you land? Is Cowboy Bebop the rightful number one space anime, or did I bury your favorite space anime too far up the list? Drop your own ranking in the comments and tell me which show you would blast off with first.
