Michael Cretu (Romanian: Mihai Crețu pronounced [miˈhaj ˈkret͡su]; born 18 May 1957, Bucharest, Romania) is a Romanian–German musician. He is also known as Curly, MC or Curly M.C. because of his fair curled hair (creț means "curly" in Romanian).

He has collaborated with many musicians along his career, including his ex-wife Sandra Lauer (Sandra Cretu from marriage in 1988), musician Peter Cornelius, guitarists Manfred Thiers and Jens Gad, Frank Peterson, David Fairstein (Fabrice Guitad), D.J. André Tanneberger (from the A.T.B. Music Project), Peter Ries, Bernt Moehrle, singer Ruth-Ann Boyle, and Andru Donalds, who produced the single Mishale in 1995.
