In enzymology, an acetoacetyl-CoA reductase (EC 1.1.1.36) is an enzyme that catalyzes the chemical reaction

(R)-3-hydroxyacyl-CoA + NADP⁺ $\rightleftharpoons$ 3-oxoacyl-CoA + NADPH + H⁺

Thus, the two substrates of this enzyme are (R)-3-hydroxyacyl-CoA and NADP⁺, whereas its 3 products are 3-oxoacyl-CoA, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is (R)-3-hydroxyacyl-CoA:NADP⁺ oxidoreductase. Other names in common use include acetoacetyl coenzyme A reductase, hydroxyacyl coenzyme-A dehydrogenase, NADP⁺-linked acetoacetyl CoA reductase, NADPH:acetoacetyl-CoA reductase, D(−)-beta-hydroxybutyryl CoA-NADP⁺ oxidoreductase, short chain beta-ketoacetyl(acetoacetyl)-CoA reductase, beta-ketoacyl-CoA reductase, D-3-hydroxyacyl-CoA reductase, and (R)-3-hydroxyacyl-CoA dehydrogenase. This enzyme participates in butanoate metabolism.
