Spring Heel Jack is an English electronic music group consisting of John Coxon and Ashley Wales. Wales was formerly a composer of "serious" music, an influence that carried over to much of the duo's work. Their first three drum and bass albums released during the 1990s earned positive reviews for their innovate take on the genre.

More recently they have moved away from drum and bass to collaborate with free improvisers and free jazz players from the United States and Europe, producing three albums for the Thirsty Ear label's Blue Series of adventurous cross-genre efforts.
