"Rejoined" is the 78th episode of the American science fiction television series Star Trek: Deep Space Nine, the sixth of the fourth season. It originally aired on October 30, 1995, in broadcast syndication. The episode received a record volume of feedback from viewers for the series, both positive and negative, as it marked one of the first televised lesbian kisses.

Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy. The plot of "Rejoined" expands on the Trill species, of which Jadzia Dax is a member. They are formed of a host and a symbiont, with the symbiont passed from host to host as the previous one dies. In the episode, Dax is reunited with Lenara Kahn, the ex-wife of one of its former hosts. The two struggle with their feelings for one another because of the taboo in their species against reuniting with loved ones of former hosts.

The episode was the first that writers Ronald D. Moore and René Echevarria wrote together, and it was directed by main cast member Avery Brooks. In the first draft, Dax's former partner was written as male, but after this was changed, the story was cleared through studio executives. The Trill taboo was intended to be an allegory for homosexuality and homophobia. "Rejoined" received a Nielsen rating of seven percent on the first broadcast in syndication. Reviews have been mostly positive towards the episode because of its message, but there was criticism that the plot was not exciting enough and there was a negative reaction from some viewers.
