The Yamaha DT50M is an entry-level 50 cc (3.1 cu in) motorcycle in the Yamaha DT50M series, produced from 1978 to 1981. It is a dual-purpose street/trail bike primarily aimed at novice motorcyclists.

The DT50M has twin rear shocks and 19″/17″ front and rear wheels. The DT50MX, which is a later model of the DTM50M, has larger 21″/18″ wheels and a mono shock rear suspension. After its production and high sales, Yamaha decided to produce a street bike variant of the DT50M, which was given the model number RD50M.

The Yamaha DT50MX was given similar treatment to the Yamaha RD50MX.
