Carvone reductase (EC 1.3.99.25) is an enzyme with systematic name (+)-dihydrocarvone:acceptor 1,6-oxidoreductase.^[1] This enzyme catalyses the following chemical reaction

(1) (+)-dihydrocarvone + acceptor ${\displaystyle \rightleftharpoons }$ (-)-carvone + reduced acceptor

(2) (-)-isodihydrocarvone + acceptor ${\displaystyle \rightleftharpoons }$ (+)-carvone + reduced acceptor

This enzyme participates in the carveol and dihydrocarveol degradation pathway of the Gram-positive bacterium Rhodococcus erythropolis DCL14.
