Gert-Jan Prins (born 1961, IJmuiden) is a Dutch musician active in free improvisation.
Initially a free jazz percussionist, Prins now focuses on producing and manipulating sound, especially white and pink noise, using a collection of custom-built FM radio transmitters and receivers, similar to the instruments of American composer David Tudor.
Prins is a member of M.I.M.E.O., a twelve-piece electronic orchestra led by Keith Rowe (formerly of the British free-improvisation trio AMM). He has groups with synthesizer players Thomas Lehn and Thomas Ankersmit, pianist Cor Fuhler and composer and reed player Peter van Bergen.
