Seed of Chucky, also known as Child's Play 5: Seed of Chucky or Child's Play 5, is a 2004 horror comedy film, which is the fifth entry in the Child's Play series. The film was written and directed by Don Mancini, who created Child's Play and has written all sequels to date. With this entry, Mancini marked his directorial debut.

Seed of Chucky follows the events of Bride of Chucky and stars Jennifer Tilly (who plays herself and also voices Tiffany), Billy Boyd (as the voice of Glen/Glenda), Brad Dourif (as Chucky), Steve Lawton (as Stan). The film features rapper Redman, cult director John Waters, and S Club 7 star Hannah Spearritt.

The film, shot in Romania, continues the series' evolution from the pure-horror genre of the first film to a hybrid horror-comedy. Besides spoofing other horror films, the film references domestic dramas and tabloid television. This film also counts as the first film in the series to contain nudity. A sixth installment in the series titled Curse of Chucky is set to go into production in September 2012; the film will also be the first direct-to-DVD installment. A reboot of the series is also set to go into production within 2013. Brad Dourif has been cast to reprise his voice role of Chucky in Curse of Chucky and the reboot.
