"Future's End" is a two-part episode from the third season of the American science fiction television series Star Trek: Voyager, the eighth and ninth of the season and the 50th and 51st overall. "Future's End" made its debut on American television in November 1996 on the UPN network in two separate broadcasts, on November 6 and 13, 1996.

Set in the 24th century, the series follows the adventures of the Federation starship Voyager during its journey home to Earth, having been stranded tens of thousands of light-years away. In this episode, Voyager is thrown back to Earth in 1996 and must find a way back to the 24th century while making sure they do not cause a disaster in the 29th century in the process.

Part one was directed by David Livingston and part two by Cliff Bole, with a story by Brannon Braga and Joe Menosky. Guest stars include Sarah Silverman and Ed Begley Jr.

A small ship with a Federation signature emerges from a temporal rift in front of the starship Voyager. Its pilot identifies himself as Captain Braxton (Allan Royal) from the 29th century in the timeship Aeon. He has come to destroy Voyager, believing it to be the cause of a temporal explosion that will wipe out most of the Solar System in his time. Voyager fights off Braxton's attack, resulting in Braxton being sent back through the rift. Voyager and its crew are also pulled into the rift and find themselves on Earth in 1996.

Braxton crashes in 1967, where Henry Starling (Ed Begley Jr.) finds Aeon and copies its technology, allowing him to found a company, Chronowerx Industries, and start the micro-computer revolution. In 1996, a young astronomer named Rain Robinson (Sarah Silverman) who works at the Griffith Observatory in Los Angeles detects Voyager in high orbit and assumes it to be extraterrestrial life. Her work is funded by Starling, but against his instructions, she attempts to contact Voyager by transmitting a greeting to it, alarming the crew. The Voyager crew tracks her location to the Observatory and Captain Janeway, Commander Chakotay, Lt. Tuvok (Tim Russ), and Lt. Paris (Robert Duncan McNeill), decide to beam down to Los Angeles. Tuvok and Paris save Robinson from a hitman Starling dispatched to kill her.

Janeway and Chakotay investigate Starling and his business. They identify a homeless man as Captain Braxton, who explains the rise of Starling to them. Ultimately, they learn that Starling's planned attempt to travel to the 29th century using Braxton's timeship will be the true cause for the temporal explosion, because Starling lacks the knowledge needed to properly calibrate the timeship.

Janeway and Chakotay secretly enter Starling's Chronowerx office where they find the Aeon, just as Starling walks in on them. Starling ignores Janeway's warning not to use the timeship and tries to kill them, but the officers are beamed aboard Voyager. When Voyager tries to beam up the timeship, Starling uses his own transporter beam to access Voyager's computer and study its systems, including stealing the Doctor's program from Sickbay. Worse still, Voyager has been sighted and filmed, since the ship had to descend low into Earth's atmosphere to beam Janeway and Chakotay aboard.

Following Starling's computer attack, Voyager is badly damaged, leaving Paris and Tuvok stranded on Earth with Robinson. Paris convinces her to help by claiming that he and Tuvok are government agents trying to recover highly advanced technology that was stolen by Starling. Robinson, prompted by Paris and Tuvok, arranges to meet Starling at a public park. To keep an eye on the Doctor, Starling equips the Doctor with a piece of 29th-century technology, a "Mobile Holo-Emitter", which allows him to move around without having to rely on fixed emitters.
