4-nitrocatechol 4-monooxygenase (EC 1.14.13.166) is an enzyme with systematic name 4-nitrocatechol,NAD(P)H:oxygen 4-oxidoreductase (4-hydroxylating, nitrite-forming). This enzyme catalyses the following chemical reaction:

4-nitrocatechol + NAD(P)H + H + O₂ ${\displaystyle \rightleftharpoons }$ 2-hydroxy-1,4-benzoquinone + nitrite + NAD(P)+ + H₂O

4-nitrocatechol 4-monooxygenase contains flavin adenine dinucleotide (FAD).
