Twilight of the Cockroaches (ゴキブリたちの黄昏, Gokiburi-tachi no Tasogare) is a 1987 Japanese fantasy drama film written and directed by Hiroaki Yoshida that combines live-action footage with animation. The plot concerns a society of cockroaches who live peacefully in the apartment of a bachelor named Saito, until a woman moves in and the humans begin to exterminate the cockroaches. The cockroaches are depicted through animation, and the humans are depicted through live-action footage.

Director Yoshida has stated that the film is "about Japan" and that the "concept of a 'hated' species is like the racial and cultural enmity with which Japan is perceived". In his New York Times review, Vincent Canby wrote: "The publicity material for Twilight of the Cockroaches describes the film as an allegory about the fate in store for affluent Japan if it doesn't meet its international responsibilities. The film may read that way in Japan. In this country, it looks somewhat darker and more muddled".

The English dub of the film was produced by Streamline Pictures. During the early-to-mid 1990s, the film was shown frequently on Turner Broadcasting stations such as TBS, TNT, and Cartoon Network, often paired with Vampire Hunter D and Robot Carnival. As a result, it was one of the first exposures to anime for many American anime fans.

The soundtrack is by Morgan Fisher.

The film was originally released on VHS and LaserDisc by Lumivision in 1991.

The film was released on to DVD by Discotek Media on February 26, 2019.
