Coroner is a Swiss thrash metal band from Zürich formed in 1983, better known for the lineup formed in 1985. They garnered relatively little attention outside of Europe. The band broke up in 1996, but reformed 14 years later. The band has performed at multiple live venues and festivals around worldwide since 2011, and as of 2023, they are working on their first studio album in more than three decades.

Coroner's music combines elements of thrash, classical music, avant-garde music, progressive rock, jazz, and industrial metal with suitably gruff vocals. With their increasingly complex style of progressive rock-infused thrash, they have been called "the Rush of thrash metal", and along with Voivod and Watchtower, the band has been credited for helping pioneer the subgenre of "technical thrash metal" (also called "progressive thrash metal") during the mid-to-late 1980s. Coroner's sound then progressed and the production became more refined, resulting in a more progressive sound on their last three albums, No More Color (1989), Mental Vortex (1991) and Grin (1993).
