Unimatrix One also known as the Central Unicomplex is a Borg Unicomplex that serves as the heart of the Borg Collective. This Borg complex is the home of the Borg Queen and thousands of Borg starships and billions of Borg drones.

Unimatrix One is first shown in the Voyager episode Dark Frontier. Seven of Nine is taken here to meet the Queen. A rescue team from the USS Voyager later infiltrated the Unicomplex and retrieved Seven.

In the Voyager finale Endgame, the Unicomplex is severely damaged (possibly destroyed) when a version of Kathryn Janeway from the future sacrifices herself to infect the Borg Queen with a virus that destroys her.
