Dopamine beta-hydroxylase (DBH), also known as dopamine beta-monooxygenase, is an enzyme (EC 1.14.17.1) that in humans is encoded by the DBH gene. Dopamine beta-hydroxylase catalyzes the chemical reaction:

The three substrates of this enzyme are 3,4-dihydroxyphenethylamine, ascorbate, and O₂, whereas its three products are noradrenaline, dehydroascorbate, and H₂O.
