In enzymology, an aryl-alcohol dehydrogenase (NADP<sup>+</sup>) () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are an aromatic alcohol and oxidised nicotinamide adenine dinucleotide phosphate (NADP<sup>+</sup>). Its products are the corresponding aromatic aldehyde, reduced NADPH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The systematic name of this enzyme class is aryl-alcohol:NADP<sup>+</sup> oxidoreductase. Other names in common use include aryl alcohol dehydrogenase (nicotinamide adenine dinucleotide, phosphate), coniferyl alcohol dehydrogenase, NADPH-linked benzaldehyde reductase, and aryl-alcohol dehydrogenase (NADP<sup>+</sup>).
