Flavonoid 3',5'-hidroksilaza (EC 1.14.13.88, flavonoidna 3',5'-hidroksilaza) je enzim sa sistematskim imenom flavanon,NADPH:kiseonik oksidoreduktaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju

flavanon + 2 NADPH + 2 H+ + 2 O2 {\displaystyle \rightleftharpoons } 3',5'-dihidroksiflavanon + 2 NADP+ + 2H2O (sveukupna reakcija)
(1a) flavanon + NADPH + H+ + O2 {\displaystyle \rightleftharpoons } 3'-hidroksiflavanon + NADP+ + H2O
(1b) 3'-hidroksiflavanon + NADPH + H+ + O2 {\displaystyle \rightleftharpoons } 3',5'-dihidroksiflavanon + NADP+ + H2O

Ovaj enzim je hem-tiolatni protein (P-450). 3',5'-dihidroksiflavanon se formira putem 3'-hidroksiflavanona.
