Chronology
← Preceded by Followed by → "Army of Ghosts" "The Runaway Bride"

"Doomsday" is the thirteenth and final episode in the second series of the revival of the British science fiction television programme Doctor Who. It was first broadcast on 8 July 2006 and is the conclusion of a two-part story; the first part, "Army of Ghosts", was broadcast on 1 July 2006. The two-part story features the Daleks, presumed extinct after the events of the 2005 series' finale, and the Cybermen, who appeared in a parallel universe in "Rise of the Cybermen" and "The Age of Steel". Both species unexpectedly arrive on Earth at the conclusion of "Army of Ghosts".

The concept of the Daleks and the Cybermen both appearing on-screen was first proposed in 1967, but was vetoed by Terry Nation, the creator of the Daleks. The episode is the first conflict between the two species in Doctor Who's 45-year history, and features Billie Piper's last appearance in the lead companion role as Rose Tyler; the final regular appearance of Noel Clarke as Rose's ex-boyfriend and previous companion Mickey Smith; and the final regular appearances of Camille Coduri and Shaun Dingwall as Rose's parents, Jackie and Pete Tyler. The episode was filmed in December 2005 and January 2006, alongside the episodes "Rise of the Cybermen" and "The Age of Steel".

The plot consists mostly of the Daleks and Cybermen waging a global war, with humanity caught in the crossfire. The Doctor, the Tyler family, and Mickey Smith fight for their lives trying to reverse the situation. They are successful, but at an emotional cost to the Doctor and Rose, as they are left in separate universes.
