Michael Friedrich Möllenbeck (12 December 1969 – 2 November 2022) was a German discus thrower.

[1] Möllenbeck's greatest achievements were two World Championship bronze medals, and his bronze at the 2005 World Championships was especially welcome as Germany struggled to win medals.

His personal best throw was 67.64 metres, achieved in June 2002 in Dortmund.

This ranks him seventh among German discus throwers, behind Jürgen Schult, Lars Riedel, Wolfgang Schmidt, Armin Lemme, Hein-Direck Neu and Alwin Wagner.

[2] Möllenbeck married fellow discus thrower Anja Gündler in 1996.
