|Rebecca Wood as Jenna McFarland|
|Species:||Trill / Human|
Lieutenant Jenna McFarland was a Trill/human hybrid who served in Starfleet during the 24th century. She was assigned as a conn officer aboard the USS Excelsior in 2377. Even though McFarland was the head of her department, she frequently took the unpopular duty shifts, and was rarely on alpha watch.
During the Final Days of the Archin conflict in 2386, Admiral Shelby gave temporary command of the USS Helena to McFarland. During which Captain McFarland disobeyed direct orders to return to base and undertake a rescue mission to save Lieutenant Dias and Dr. Henglar from the Orion Syndicate vessel Vaptest.
McFarland was a classmate and friend of Corey Aster at the Academy. McFarland, along with Jeremy Aster and Jason Munoz, told Ro Nevin they were worried about Corey Aster, who had gone missing. Under Ro's command, the quartet found Corey Aster being attacked by three townies for a prank he'd played on them days earlier. (Star Trek: The Cantabrian Expeditions: "Dream a Little Dream of Me")
