Markus Reuter (born Lippstadt, Germany, 1972) is a German multi-disciplinary musician, composer, record producer and instrument designer. His work spans (and frequently fuses) art rock, loop music, contemporary classical music and alternative pop.

Reuter is a member of multiple ongoing bands and projects (including centrozoon, Tuner, Stick Men, The Crimson ProjeKct and Europa String Choir).
