"Legacy" is the 80th episode of the syndicated American science fiction television series Star Trek: The Next Generation, the sixth episode of the fourth season. It marked the point at which the series surpassed the number of episodes in the original series.

The Enterprise crew is caught in the midst of a civil war on Turkana IV, former crew member Tasha Yar's homeworld. While negotiating with one of the factions, they discover that the faction's representative is Tasha's younger sister, Ishara.

The Enterprise, under the command of Captain Jean-Luc Picard (Patrick Stewart), responds to a distress call from the Federation freighter Arcos which has suffered from engine failure and taken emergency orbit around the colonized planet Turkana IV, the birthplace of the Enterprise's former chief of security, Tasha Yar. The Enterprise arrives just as the Arcos explodes, but find a trail left behind by the freighter's escape pod leading to the colony. Turkana IV's government collapsed 15 years before, and the last Federation ship to visit six years earlier was warned by the colony's warring factions that any trespassers transporting down to the planet would be executed. As the freighter crew's lives are in danger, Picard decides a rescue must be attempted.

Commander Riker (Jonathan Frakes) leads an away team to the surface, where they find the colonists initially unperturbed by their presence, but soon end up in a standoff with one of the colony's two remaining warring factions, the Coalition. Their leader Hayne (Don Mirault) reveals that the other faction, the Alliance, holds the Arcos survivors hostage, and offers the Enterprise their support in exchange for Federation weapons, which Riker rejects. However, Hayne, after learning of Tasha Yar's service aboard the Enterprise, instead offers Ishara Yar (Beth Toussaint), claiming she is Tasha's sister, as a liaison. Picard accepts Ishara aboard, and while the crew is initially skeptical, DNA tests support her claims, and she gradually gains the crew's trust. Commander Data (Brent Spiner), who was especially close to Tasha, develops a friendship with Ishara, while Ishara seems prepared to leave her life on the colony behind.
