Jazz Sabbath is an English jazz trio, with a fictional backstory that they are from the late sixties. The band was created by Adam Wakeman, touring keyboard and guitar player for Black Sabbath (2004–2017) and Ozzy Osbourne band member (2004–present). Jazz Sabbath plays jazz renditions of Black Sabbath songs, claiming to be the original writers of those songs and accusing Black Sabbath of plagiarism.

The band first appeared in a mockumentary on YouTube in February 2020. In this short film band leader Milton Keanes (Adam Wakeman) was interviewed by actor Robert Powell about the early days of Jazz Sabbath, their cancelled debut album and the alleged theft of their songs by Black Sabbath. This album was later released as an actual album on 10 April 2020.
