Steroidna D-izomeraza (EC 5.3.3.1, hidroksisteroidna izomeraza, steroidna izomeraza, Delta5-ketosteroidna izomeraza, Delta5(or Delta4)-3-keto steroidna izomeraza, Delta5-steroidna izomeraza, 3-oksosteroidna izomeraza, Delta5-3-keto steroidna izomeraza, Delta5-3-oksosteroidna izomeraza) je enzim sa sistematskim imenom 3-oksosteroid Delta5-Delta4-izomeraza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju

3-okso-Delta5-steroid ⇌ {\displaystyle \rightleftharpoons } 3-okso-Delta4-steroid

Ovu aktivnost katalizuje nekoliko enzima.
