Linoleate 8R-lipoxygenase (EC 1.13.11.60, linoleic acid 8R-dioxygenase, 5,8-LDS (bifunctional enzyme), 7,8-LDS (bifunctional enzyme), 5,8-linoleate diol synthase (bifunctional enzyme), 7,8-linoleate diol synthase (bifunctional enzyme), PpoA) is an enzyme with systematic name linoleate:oxygen (8R)-oxidoreductase. This enzyme catalyses the following chemical reaction

linoleate + O₂ ${\displaystyle \rightleftharpoons }$ (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate

Linoleate 8R-lipoxygenase contains heme.
