Cause of Death is the second album by American death metal band Obituary. It was released on September 19, 1990. Cause of Death is considered a classic album in the history of death metal. The artwork was done by artist Michael Whelan. It is their first release with longtime member Frank Watkins on bass, and also their first and only album with guitarist James Murphy, previously of Death. Murphy did not contribute to the songwriting as the riffs he showed to the band would end up appearing on Disincarnate's Dreams of the Carrion Kind.
