Kerry Dylan McCoy is an American musician, best known as the guitarist of San Francisco–based blackgaze band Deafheaven.

Deafheaven is an American post-metal band formed in 2010. Originally based in San Francisco, the group began as a two-piece with singer George Clarke and guitarist Kerry McCoy, who recorded and self-released a demo album together. Following its release, Deafheaven recruited three new members and began to tour. Before the end of 2010, the band signed to Deathwish Inc. and later released their debut album Roads to Judah, in April 2011. They popularized a unique style blending black metal, shoegaze, and post-rock, among other influences, later called "blackgaze" by reviewers.
