Martín Méndez (born 6 April 1978) is a Uruguayan Swedish musician. He is the bassist of the progressive metal band Opeth and the second-longest-serving member of the band, behind frontman Mikael Åkerfeldt.
Méndez has been a member of several other bands, including Fifth to Infinity, Proxima and Vinterkrig. He joined Opeth right before the recording of their third album My Arms, Your Hearse (1998) began. However, time conflicts kept him from playing on the album, so the bass lines were recorded by Mikael Åkerfeldt. Méndez then learned the bass parts and played bass for the few subsequent live dates done for the album. His first real recording with Opeth was their fourth studio album, Still Life (1999). He has been with the band ever since.
Méndez uses four-string fretted & fretless Fender Jazz Bass guitars as well as Sandberg bass guitars for live and studio work.
