The Bajorans are a fictional species in the science-fiction Star Trek franchise. They are a humanoid extraterrestrial species native to the planet Bajor, who have a long-standing enmity with the Cardassians, owing to decades of subjugation under a military dictatorship which saw many of their species enslaved or forced into exile away from their homeworld. They were first introduced in the 1991 episode "Ensign Ro" of Star Trek: The Next Generation, and subsequently were a pivotal element of Star Trek: Deep Space Nine and also appeared in Star Trek: Voyager and Star Trek: Picard.
