7 Greatest American Sci-Fi Shows Of All Time

by

Science fiction has given us many unforgettable stories, and some of the best have come in the form of TV shows. While great sci-fi originates from around the globe, the United States seems to be a particularly strong source. Many of the most beloved and influential sci-fi TV shows of all time were created or take place in the US. From the beginning of television, America has consistently produced iconic shows, and science fiction is a prime example of this.

Science fiction covers a huge range of ideas and settings, so American sci-fi isn’t always based in the United States. Some of the best shows imagine humanity’s future among the stars, while others are set much closer to home. Here’s a look at some of the greatest American sci-fi shows ever made, regardless of where they’re set.

7) The Expanse (2015-2022)

Many consider The Expanse to be one of the best science fiction TV shows ever made. Adapted from the book series by James S. A. Corey, the show centers on a group of characters who uncover a massive interstellar plot and new alien technology. It became incredibly popular, and fans successfully campaigned to prevent its cancellation, demonstrating how much the show means to sci-fi enthusiasts.

6) Westworld (2016-2022)

Even though it hasn’t been on the air for very long, Westworld is frequently considered one of the greatest science fiction TV shows ever made. The series, inspired by the 1973 film of the same name, centers on the people and lifelike androids who live in and run a Wild West-themed amusement park. It’s a story full of thought-provoking ideas and ethical questions, balanced with exciting action and moments of suspense. Westworld explores fascinating concepts using classic sci-fi elements, solidifying its place as a top American sci-fi show.

5) Star Trek: The Original Series (1966-1969)

As a huge sci-fi fan, I always say that everyone needs to experience Star Trek at least once. It’s the show that started it all, and while it’s now known as The Original Series, even with effects that haven’t aged perfectly, it’s still one of the greatest American sci-fi shows ever made. It really broke new ground with its forward-thinking ideas and stories, and that’s why sci-fi fans like me hold Star Trek: The Original Series in such high regard.

4) Stranger Things (2016-2025)

Combining science fiction, horror, action, and teen drama, Stranger Things quickly became a huge cultural hit. It achieved massive popularity worldwide and became one of the defining shows of its era, with its five seasons being among the most popular and discussed in science fiction television history. Stranger Things is truly unique, solidifying its place as one of the best sci-fi shows in recent years.

3) Battlestar Galactica (2005-2009)

The 2000s reimagining of Battlestar Galactica built upon the foundation of the original series, but quickly became a landmark achievement in science fiction. Critics and audiences alike praised its complex themes, epic storyline, and impressive visual effects. Many consider it one of the greatest American sci-fi shows ever made, and it significantly influenced the standards for the entire genre.

2) The X-Files (1993-2018)

While many science fiction shows are enjoyable, only a few truly leave a lasting impact. The X-Files is one of those shows, captivating a generation with its mix of science fiction and horror. It also revitalized the genre by emphasizing its scary potential. By focusing on government agents investigating threats from aliens, robots, and other sources, The X-Files wasn’t just great entertainment—it became one of the most influential American sci-fi shows of all time.

1) Star Trek: The Next Generation (1987-1994)

Many consider the 1990s a golden age for science fiction television, and Star Trek: The Next Generation is a major reason why. It successfully reintroduced the Star Trek universe to a new generation of viewers, benefiting from improvements in special effects. While staying true to the spirit of The Original Series, The Next Generation raised the bar for storytelling in sci-fi, and is often considered the greatest American sci-fi show ever made.
