Star Trek: Voyager is an American science fiction series created by Rick Berman, Michael Piller and Jeri Taylor. It aired from January 16, 1995, to May 23, 2001, on UPN, with 172 episodes over seven seasons. The fifth series in the Star Trek franchise, it served as the fourth after Star Trek: The Original Series. Set in the 24th century, when Earth is part of a United Federation of Planets, it follows the adventures of the Starfleet vessel USS Voyager as it attempts to return home to the Alpha Quadrant after being stranded in the Delta Quadrant on the far side of the galaxy.

Paramount Pictures commissioned the series after the cancellation of Star Trek: The Next Generation to accompany the ongoing Star Trek: Deep Space Nine. They wanted it to help launch UPN, their new network. Berman, Piller, and Taylor devised the series to chronologically overlap with Deep Space Nine and to maintain thematic continuity with elements that had been introduced in The Next Generation and Deep Space Nine. The complex relationship between Starfleet and ex-Federation colonists known as the Maquis was one such element and a persistent central theme. Voyager was the first Star Trek series to feature a female commanding officer, Captain Kathryn Janeway (Kate Mulgrew), as the lead character. Berman was head executive producer in charge of the overall production, assisted by a series of executive producers: Piller, Taylor, Brannon Braga, and Kenneth Biller.

Set in a different part of the galaxy from preceding Star Trek shows, Voyager gave the series' writers space to introduce new alien species as recurring characters, namely the Kazon, Vidiians, Hirogen, and Species 8472. During the later seasons, the Borg—a species created for The Next Generation—were introduced as the main antagonists. During Voyager's run, various episode novelizations and tie-in video games were produced; after it ended, various novels continued the series' narrative.
