Dragon Ball Z: Lord Slug, also known by its Japanese title Dragon Ball Z - Super Saiyan Son Goku (Japanese: ドラゴンボールZ 超(スーパー)サイヤ人だ孫悟空, Hepburn: Doragon Bōru Zetto Sūpā Saiyajin da Son Gokū^?) is the fourth Dragon Ball Z feature movie. It was originally released in Japan on March 9, 1991 between episodes 81 and 82 at the Toei Anime Fair as part of a double feature with the first Magical Tarurūto-kun movie. An American English dub was produced by Funimation and released to VHS and DVD on August 7, 2001. Two other English dubs were also produced, one in France by AB Groupe done for European markets which was released under the misspelt title Super Saiya Son Goku, and another one for a Malaysian VCD release by Speedy Video which had the title Super Saiya People, Goku. While the Malaysian dub's cast remains unknown, the AB Groupe dub is now believed to have been recorded by English-speaking actors based in France who have also done voices for animated television series such as Code Lyoko and Chris Colorado.

This is the first Dragon Ball Z movie to be dubbed with Funimation's English voice cast, and also the first to have songs by bands replace the original Japanese score (although the original Japanese score was restored for tracks on later releases). It was later remastered and released in a Double Feature set with Tree of Might on Blu-Ray and DVD on May 27, 2008. The film was released to DVD again on November 1, 2011 in a remastered box set containing the first five Dragon Ball Z movies.
