Still Reigning is a live performance DVD by the thrash metal band Slayer, released in 2004 through American Recordings. Filmed at the Augusta (Maine) Civic Center on July 11, 2004, the performance showcases Slayer's 1986 album, Reign in Blood, played in its entirety with the four original band members on a set resembling their 1986 Reign in Pain Tour. Still Reigning was voted "best live DVD" by the readers of Revolver magazine, and received gold certification in 2005.

The DVD is notable for the finale, which features Slayer covered in stage blood while performing the song "Raining Blood", leading to a demanding audio mixing process plagued by production and technical difficulties. The DVD's producer Kevin Shirley spent hours replacing cymbal and drum hits one-by-one. He publicly aired financial disagreements he had with the band and criticized the quality of the recording, and as a result was allegedly subjected to threats and insults from people associated with the band.
