René Wenzel (born 20 April 1960, Copenhagen, Denmark) is a Danish cycle racing coach, working as a consultant.
Wenzel went to school at Bispebjerg Skole and Efterslaegtselskabets Gymnasium before moving to Belgium in 1979, and to France in 1980, to race as a professional cyclist.
Wenzel became first Danish directeur sportif of a UCI professional team in 1993, when he joined Saturn.
Three former athletes, Greg Strock, Erich Kaiter and Gerrik Latta accused Wenzel, along with Chris Carmichael, Cycling USA and Angus Fraser, of treating them with illegal drugs in 1990, feeding them pills and giving them injections, such as cortisone, an immunosuppressant; Greg Strock in 2000, Erich Kaiter later in 2001 and Gerrik Latta.
In November 2007, the Malaysian National Cycling Federation offered Wenzel the position of director of coaching, but it never came to fruition.
