Katehol oksidaza (EC 1.10.3.1, difenolna oksidaza, o-difenolaza, polifenolna oksidaza, pirokateholna oksidaza, dopa oksidaza, kateholaza, o-difenol:kiseonik oksidoreduktaza, o-difenolna oksidoreduktaza) je enzim sa sistematskim imenom 1,2-benzendiol:kiseonik oksidoreduktaza.[1][2][3][4][5][6][7][8][9] Ovaj enzim katalizuje sledeću hemijsku reakciju:

2 katehol + O2 {\displaystyle \rightleftharpoons } 2 1,2-benzohinon + 2H2O

Ovaj enzim je tip 3 bakarni protein koji ekskluzivno katalizuje oksidaciju katehola do o-hinona.
