Hydrazine oxidoreductase (EC 1.7.99.8, HAO (ambiguous)) is an enzyme with systematic name hydrazine:acceptor oxidoreductase. This enzyme catalyses the following chemical reaction

hydrazine + acceptor

\rightleftharpoons

N₂ + reduced acceptor

Hydrazine oxidoreductase is involved in the pathway of anaerobic ammonium oxidation in anammox bacteria.
