Protoporfirinogen oksidaza (EC 1.3.3.4, protoporfirinogenska IX oksidaza, protoporfirinogenaza, PPO, Protox, HemG, HemY) je enzim sa sistematskim imenom protoporfirinogen-IX:kiseonik oksidoreduktaza.[1][2][3][4][5][6][7][8][9] Ovaj enzim katalizuje sledeću hemijsku reakciju

protoporfirinogen IX + 3 O2 {\displaystyle \rightleftharpoons } protoporfirin IX + 3H2O2

Ovaj enzim je najmanje zastupljen u biosintezi hlorofila i hema. Postoje dva izoenzima kod biljki: jedan u plastidima i drugi u mitohondrijama. On je meta ftalimidnog i difenileterskog tipa herbicida.
