Marten Laciny (born 4 December 1982), better known by his stage name Marteria, is a German hip hop artist from Rostock.

His stage name is derived from his first name, and also the Latin word ‘materia’ meaning ‘matter’ or ‘substance’. He has met with success in Germany (his 2012 collaboration with Yasha and Miss Platnum, Lila Wolken, reached Number 1 in the German music charts) and the single Verstrahlt, featuring Yasha, was included in the console game FIFA 12.

His alternative stage name and alter ego is Marsimoto (see section). Before his music career, he was a successful football player and male model.
