Mårten Hans Hagström[1] (born 27 April 1971) is a Swedish musician, best known as the rhythm guitarist for the extreme metal band Meshuggah.

[2] He joined the band after the release of their first album, which allowed Jens Kidman to focus on his vocal performances and give up rhythm guitar duties.

Hagström has cited Rush, James Hetfield, Squarepusher, Autechre, Strapping Young Lad, and GISM as influences.

Although Thordendal plays most of Meshuggah's guitar solos, the two of them share songwriting duties more or less equally, with Hagström notably contributing "Nebulous" from Nothing, "Acrid Placidity" from Destroy Erase Improve, and "Neurotica" from Chaosphere.

The group found the Nevborns to be somewhat unstable while touring and when Ibanez communicated a desire to try building them 8-string guitars they accepted the offer.
