Seven of Nine, Tertiary Adjunct of Unimatrix Zero One is a fictional character from the Star Trek universe, played by Jeri Ryan in the television series Star Trek: Voyager.

Born as Annika Hansen in Tendara Colony in 2348 to Magnus and Erin Hansen, a pair of ethologists, Seven of Nine was assimilated at the age of six on the USS Raven. The last record of the Hansens was at Deep Space 4 in the Omega sector, where they refused to file a flight plan. The Borg Collective was all she knew, and provided her with a sense of order. After serving as a representative of the Borg during a Borg-Voyager alliance, Seven was disconnected from the Collective by Captain Kathryn Janeway, Commander Chakotay and Chief Engineer B'Elanna Torres in order to prevent Seven's betrayal and an ensuing assimilation of the USS Voyager. This occurred in the Star Trek: Voyager episode "Scorpion" (Ep 3x26-4x01). Although given the opportunity to be addressed once again as Annika Hansen, Seven chose to retain her Borg designation.

Following her disconnection, she found in Captain Janeway a mentor who helped her become more human with each episode. The Doctor also provided valuable guidance in enabling her to develop her social skills and thus "blend in" with the crew of Voyager. The Doctor subsequently fell in love with Seven, but she did not reciprocate these feelings. Her character's storyline instead took an unexpected twist in the final episodes of the series: she fell in love with Commander Chakotay after running simulations with a holographic Chakotay, and was set to marry the real one as the series ended. This 11th hour development which first manifested itself midway through the seventh season, upset many fans, namely those who wanted to see the romantic relationship from the first seasons between Janeway and Chakotay revived, and those who saw lesbian subtext between Janeway and Seven.

Star Trek novelist Christie Golden corrected this "mistake" in her books Homecoming and The Farther Shore. Naturally these books disappointed the fans who liked the idea of Seven and Chakotay.

At the end of the Voyager series, Seven had surgery to one of her implants to allow her to properly use emotions (and, it is strongly implied, become capable of experiencing sexual relationships, although this contradicts an early appearance in which she invites Harry Kim to "copulate" with her, though it could be suggested that the recently "deborgified" Seven understood the word in a purely physical sense without any of the romantic connotations Kim hoped for).

While Seven proved popular with many of the show's fans, there was some criticism that the show began to focus too much on her character to the exclusion of others. Some also considered her tight-fitting costume to be too blatant an attempt to appeal to the young male demographic; if true, it was a successful gambit as the introduction of Seven of Nine is credited with saving the series from cancellation. Other common criticisms are that instead of a distinct personality, she was simply given a Vulcan-like personality which never really developed until later in the show's life, and that she was commonly used to provide technological deus ex machina.
