Martín López (born 20 May 1978 in Stockholm, Sweden) is a Swedish-Uruguayan drummer, currently a member and co-founder of progressive metal supergroup Soen, but is best known as the ex-drummer of Swedish progressive death metal band Opeth and melodic death metal band Amon Amarth.

López was born in Sweden to Uruguayan settler parents, later moving to Uruguay, then back to Sweden.

López joined Opeth in 1997, after leaving Swedish melodic death metal band Amon Amarth on whose album Once Sent From the Golden Hall he played. With Opeth, he recorded the albums My Arms, Your Hearse, Still Life, Blackwater Park, Deliverance, Damnation and Ghost Reveries.

Due to health reasons, López left Opeth permanently on 12 May 2006, to be replaced by Martin Axenrot. Lopez had not been actively involved with the band since the recording of Ghost Reveries wrapped in the summer of 2005. Lopez then shifted concentration to his old band, Fifth to Infinity. On 28 May 2010, it was announced that Martin Lopez, bassist Steve DiGiorgio, singer Joel Ekelöf and guitarist Kim Platbarzdis had joined forces in the band Soen. Their debut album, Cognitive, was released on 15 February 2012.
