Ralf Waldmann (14 July 1966 – 10 March 2018) was a German Grand Prix motorcycle road racer.

[1][2] He returned to the 250 class the following year riding for the Aprilia team and retired from motorcycle competition after the 2002 season.

Waldmann came out of semi-retirement in 2003 and signed with the new Harris WCM MotoGP team, but quit before the year began after failing to adapt to the new four-stroke Grand Prix bikes.

On a drying track, he came from nearly a whole lap down to win at the final corner at the notoriously slippery Donington Park circuit.

[3] In 2009, he joined Martin Wimmer in buying out the motorbike manufacturing company MZ, from the Hong Leong Group.
