Jazzhus Montmartre is a jazz club in Copenhagen, Denmark. Many jazz musicians, including Dexter Gordon, Stan Getz, and Chet Baker, have performed there. It is sometimes called Cafe Montmartre. The Montmartre was located first in Dahlerupsgade, then from 1961 on Store Regnegade, and since 1976 at Nørregade 41 before closing down in 1995. In May 2010, it reopened at Store Regnegade 19A by media executive and entrepreneur Rune Bech and jazz pianist Niels Lan Doky, who was later replaced as music director by saxophonist Benjamin Koppel and then jazz publisher Christian Brorsen. In 2016, Swedish jazz pianist Jan Lundgren was appointed artistic director.
