Apigenin 4'-O-metiltransferaza (EC 2.1.1.75, flavonoidna O-metiltransferaza, flavonoidna metiltransferaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:5,7,4'-trihidroksiflavon 4'-O-metiltransferaza.^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

S-adenozil-L-metionin + 4',5,7-trihidroksiflavon

\rightleftharpoons

S-adenozil-L-homocistein + 4'-metoksi-5,7-dihidroksiflavon

Ovaj enzim konvertuje apigenin u acacetin. Naringenin može takođe da deluje kao akceptor, mada sporo.
