In enzymology, a d-mannitol oxidase (EC 1.1.3.40) is an enzyme that catalyzes the chemical reaction

mannitol + O₂ ${\displaystyle \rightleftharpoons }$ mannose + H₂O₂

Thus, the two substrates of this enzyme are mannitol and O₂, whereas its two products are mannose and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is mannitol:oxygen oxidoreductase (cyclizing). Other names in common use include mannitol oxidase, and D-arabitol oxidase.
