The 10 Best Sci-Fi Shows You Can Stream on Prime Video Right Now

When people think of Prime Video's original programming, fantasy typically comes to mind first. The Lord of the Rings: The Rings of Power, The Wheel of Time, and The Legend of Vox Machina have dominated headlines with massive budgets and ambitious world-building. Meanwhile, competitors like Apple TV+ have built formidable sci-fi catalogs with shows like Silo, Foundation, and Severance.

But Prime Video's reputation as primarily a fantasy destination obscures an impressive truth: the platform hosts a stellar collection of science fiction series, both original productions and classic catalog titles. Amazon may have dropped the ball on marketing many of these shows, but the quality speaks for itself.

Here are ten of the best sci-fi shows you can stream right now with a base Prime Video subscription.

The Expanse

When discussing the best sci-fi television of the last decade, The Expanse inevitably dominates the conversation—and for good reason. Based on novels by James S.A. Corey, the series blends epic scale with political intrigue, character drama, and classic spaceship adventure to create something genuinely special.

Set in a colonized solar system where political forces vie for resources and control, the show follows the crew of the starship Rocinante as they navigate fraught interplanetary politics. Despite its far-future setting, The Expanse maintains a grounded scope that makes the stakes feel real and immediate.

Originally airing on Syfy for three seasons before cancellation, a massive fan campaign convinced Amazon to pick it up for seasons 4, 5, and 6. All six seasons are now available to stream in their entirety, and many consider it the strongest science fiction series on the entire platform.

Fallout

Video game adaptations used to demand asterisks and explanations, given the genre's history of failures. But shows like The Last of Us and Fallout have changed that narrative completely. Amazon's adaptation of the post-apocalyptic RPG franchise surprised everyone with its accuracy, craftsmanship, and humor.

Led by standout performances from Ella Purnell and Walton Goggins, the show balances multiple tones simultaneously—alternate history Americana meets Mad Max meets cybernetic Wild West. It's packed with Easter eggs for fans but accessible enough to drive massive success beyond the franchise's existing fanbase.

With Season 2 wrapped to critical acclaim and Season 3 confirmed, now's the perfect time to dive into the wasteland if you haven't already.

The Boys

This dark superhero satire is probably Prime Video's biggest success story for original series. Based on comics by Garth Ennis and Darick Robertson, The Boys hit the culture at exactly the right moment—delivering ultraviolence in the Game of Thrones era while tapping into growing MCU fatigue.

But the timing alone doesn't explain why it works so well. The performances elevate already strong material to greater heights. Antony Starr, Karl Urban, Dominique McElligott, Jack Quaid, and Erin Moriarty hammer home brutal storylines with theatrical flair.

The premise: superheroes are owned by a private corporation and granted powers by a proprietary formula, leading to mass corruption. Heroes kill, abuse, and steal with impunity while their corporate sponsor pumps out propaganda. A ragtag band of vigilantes who've been wronged by these heroes sets out to take them down, and things only get wilder from there.

Fair warning: this show isn't for the faint of heart. Here there be gore, and worse.

The Man in the High Castle

In streaming years, 2015 is ancient history. Just two years after House of Cards pioneered the streaming age, Prime Video made its own splashy entry with this Philip K. Dick adaptation about an alternate history where the Axis powers won World War II.

The United States is divided between Imperial Japan dominating the West Coast and Nazi Germany controlling the East. As oppression continues into the alternative 1960s, resistance groups rally to fight back. The sci-fi element comes from mysterious newsreels showing possible other realities—including ones where Germany and Japan lost the war.

Epic in structure with a large roster of characters, the show takes its dark world seriously, showing Nazi doctrine's evils in full effect. Sobering and tense, it's designed to weigh on you, but remains one of Amazon's most compelling original series even seven years after its conclusion.

Undone

Some sci-fi series take a few episodes to reveal their magic. With Undone, it's clear immediately. The show looks unlike anything else on Prime Video, thanks to a unique approach blending live-action performance capture, animation, and rotoscoping.

The result is a perfect marriage of medium and message. The striking, occasionally psychedelic visual style pairs beautifully with the story of Alma (Rosa Salazar), who develops a strange relationship with time following a car accident. When she begins having visions of her dead father (Bob Odenkirk), she realizes his fate isn't what she thought—and isn't necessarily permanent.

Created by two people behind BoJack Horseman, the show blends time travel, mystery, and detailed emotional character study. Both seasons (2019 and 2022) earned high critical praise, and the distinct aesthetic elevates already compelling material to truly unique heights.

Tales from the Loop

Swedish artist Simon Stålenhag deserves wider recognition. His illustrated sci-fi work is stunning, though many people's only exposure came through Netflix's 2025 disaster The Electric State—a bloated, emotionally vacant film that failed horribly to capture his vision.

Thankfully, there's a far better Stålenhag adaptation: Tales from the Loop. Released on Prime Video in 2020, it adapts his 2015 art book about rural towns littered with futuristic technology and a strange science facility called "The Loop" that causes bizarre phenomena for local inhabitants.

Body swaps, frozen time, strange robots, and more occupy eight largely self-contained episodes. Think Black Mirror or The Twilight Zone, but less interested in horror or social commentary and more focused on quiet moments and the human soul. Beautiful, melancholic, with limited dialogue and powerful visual storytelling, all underscored by an incredible soundtrack from Philip Glass and Paul Leonard-Morgan.

Outer Range

Looking for a good old-fashioned sci-fi Western and you've already rewatched Firefly too many times? Outer Range is your answer. Running two seasons between 2022 and 2024, this Prime Video original features an ensemble cast led by Josh Brolin and Imogen Poots.

Unlike space cowboy shows, this is grounded—almost like Yellowstone meets Twilight Zone. A mysterious voidlike hole appears on Royal Abbott's (Brolin) ranch, leading to increasingly bizarre situations that intertwine with the dark dramas and dangers surrounding the Abbott family.

The series didn't get much notice despite its star-studded cast and strong reviews (which improved even more in Season 2). At its best, the show uses the void to imbue grounded themes—grief, loneliness, faith, longing—with palpable eeriness.

Stargate SG-1

Obviously not a Prime Video original, but a certified sci-fi TV classic available in its 10-season entirety. Set after the original film, SG-1 turned the Stargate franchise into a titan of the genre—a clear successor to massive TV franchises like Star Trek and Doctor Who.

Space mythos and ancient alien portals had appeal in the late '90s, and they still do now. The show blends secret government operations with mythical imagery, creating something bingeable in the same way as those classic shows. Tons of slow-burn lore and recurring plot threads, with plenty of downtime for procedural elements.

The biggest appeal in a modern streaming context? The sheer volume of material available, plus numerous spin-offs for those who get hooked.

Night Sky

You've probably never heard of 2022's Night Sky. The eight-episode series came and went quickly with minimal attention from Amazon, despite being an original series. But check that cast list: Sissy Spacek and J.K. Simmons.

Similar in premise to Outer Range, the story centers on discovering a strange phenomenon on ordinary land. Retired couple Irene and Franklin discover a device in their backyard that transports them to an observation chamber overlooking an alien world. They keep it secret, using it as retirement pleasure, until a strange visitor stumbles into their lives.

Night Sky is as much a quiet drama about love and old age as it is a sci-fi thriller. The leading duo lifts what could have been forgettable far above its base potential. Pacing can be uneven and not every tangent compels, but this unique series is worth your time.

Farscape

The late '90s and early 2000s marked a transition period for TV sci-fi. Star Trek's decades of dominance through films and The Next Generation/Deep Space Nine had begun fading, leaving space for new contenders. Firefly would define cult television, and Battlestar Galactica would redefine what genre TV could be. But before either, there was Farscape.

Produced partly by The Jim Henson Company, it set itself apart immediately with alien costumes and creature designs unlike anything before or since. Campy and occasionally schlocky but also sincere, with the episodic/overarching story blend that had become popular for genre shows.

Not as many people talk about Farscape today, but it retains a devoted fandom and continues influencing modern sci-fi. James Gunn confirmed it inspired Guardians of the Galaxy. The first three seasons stream with base Prime Video subscription.

Why Prime Video Deserves More Sci-Fi Credit

Prime Video may hang its hat on fantasy spectacles, but the platform's sci-fi offerings rival any competitor. From prestige originals like The Expanse and Undone to cult classics like Farscape and Stargate SG-1, there's something for every type of science fiction fan.

The problem isn't quality—it's visibility. Amazon's marketing for many of these shows has been abysmal, leaving gems like Night Sky and Tales from the Loop to languish in obscurity. But that's where recommendations come in.

So whether you want hard sci-fi space opera, psychedelic time travel, post-apocalyptic dark comedy, or dystopian alternate history, Prime Video has you covered. You just need to know where to look.
