Triptofan 5-monooksigenaza (EC 1.14.16.4, L-triptofanska hidroksilaza, indolsirćetna kiselina-5-hidroksilaza, triptofanska 5-hidroksilaza, triptofanska hidroksilaza) je enzim sa sistematskim imenom L-triptofan,tetrahidrobiopterin:kiseonik oksidoreduktaza (5-hidroksilacija).[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju

L-triptofan + tetrahidrobiopterin + O2 {\displaystyle \rightleftharpoons } 5-hidroksi-L-triptofan + 4a-hidroksitetrahidrobiopterin

Aktivni centar sadrži mononuklearno gvožđe(II). Enzim se aktivira fosforilacijom, koju katalizuje Ca2+-aktivirana proteinska kinaza.
