Mathias Färm (born September 9, 1974, in Örebro, Sweden) is a guitar player, best known as a member of the Swedish punk rock band Millencolin.

He is also the frontman of a punk band named Franky Lee, a side-project of Millencolin.

Färm runs a studio named Soundlab Studios, which he started with the help of Mieszko Talarczyk the former lead singer of Swedish grindcore band Nasum.

This change was made because most of Millencolin's songs required two guitars on stage to duplicate the studio recorded sounds.

[1] Mathias plays most rhythm guitars on the first three Millencolin albums, but in the more recent albums, he performs most of the lead guitars, notably octave-style riffs and some solos.
