Oberursel Ur.II was a German-built 9-cylinder rotary engine rated at approximately 110 hp, developed as a licence-built version of the French Le Rhône 9J.

Produced during the mid-war period, it became one of the most widely used rotary engines in German fighter aircraft.

The engine was valued for its compact size and acceptable performance, although production quality was sometimes affected by material shortages.

Typical applications included:
• Fokker Dr.I
• Fokker D.VI

Engines of this type represent the mature stage of rotary engine use in German aviation before the transition to more advanced powerplants.
