"Army of Ghosts" is the twelfth and penultimate episode in the second series of the British science fiction television programme Doctor Who which was first broadcast on BBC One on 1 July 2006. It is the first episode of a two-part story; the concluding episode, "Doomsday", was first broadcast on 8 July.

The episode is set in London, some time after the events of the 2006 episode "Love & Monsters". In the episode, the Cybermen come to Earth from a parallel world by following a spherical ship through an interdimensional breach. The Torchwood Institute intends to open this breach further for use as an energy source.
