"The Doomsday Machine" is a second season episode of the American science fiction television series, Star Trek. It is episode number 35, production number 35, and was first broadcast on October 20, 1967, and repeated on April 19, 1968. It was written by Norman Spinrad, and directed by Marc Daniels.

In the episode, the starship Enterprise comes into contact with her sister ship, the USS Constellation, which has been heavily damaged by a huge, apparently invulnerable planet-killing machine from another galaxy. Kirk and his crew must find a means to stop the device heading for heavily populated areas of our galaxy, and deal with the heavily traumatized Commodore Decker, the Constellation's only survivor.

The Federation starship USS Enterprise, following a trail of mysteriously destroyed star systems, picks up the automated distress beacon of her sister ship, the USS Constellation and proceeds to her location. Upon arrival, the Constellation is found drifting in space, severely damaged, with her bridge uninhabitable. Captain Kirk, Chief Medical Officer Dr. McCoy, Chief Engineer Scott and a damage control team transport to the ship to evaluate her, and in Auxiliary Control discover the only member of the crew still aboard, Commodore Matt Decker, her captain, who is suffering from severe mental trauma.

Decker explains that he and his crew had discovered a giant machine, miles long, that used beams of antiprotons to tear planets apart, consuming the rubble for fuel. Their attack on the machine was ineffective and they suffered heavy damage. Decker evacuated his crew to one of the planets of the system, which the machine subsequently destroyed. Kirk theorizes that the machine is an ancient doomsday machine, which must be stopped before it reaches more populated sectors of the galaxy. The Enterprise takes the Constellation in tow and McCoy takes Decker back to the Enterprise, while Scott's damage control team attempt repairs on the Constellation's impulse engines, weapons and shields. Kirk attends to the Constellation's nonfunctional viewscreen, which, other than communications from Enterprise, will be his only means of monitoring events outside the ship.
