List RulesVote up the best science fiction TV shows that premiered their first season in 2021.

Science fiction gives us everything from brave new worlds and the wonders of space to adorable aliens and the best sci-fi shows of 2021 are no exception. From fresh additions to long-loved franchises and adaptations of science fiction classics to new stories going where no show has gone before, the new sci-fi TV series premiering in 2021 are out of this world.
 
While we wait for the big names, there are plenty of smaller sci-fi shows that are more than satisfying. Alan Tudyk as a crash-landed alien just trying to fit in in Alien Resident – which was delayed from 2020 – promises to be the perfect blend of comedy and science fiction. The new NBC science fiction series Debris gives out X-Files vibes as two government agents, one from the CIA and the other from MI6, have to work together to determine how the titular debris from an alien space ship crash is affecting the world population.
