核苷三磷酸還原酶（Ribonucleoside-triphosphate reductase）（EC 1.17.4.2ribonucleotide reductase, 2'-deoxyribonucleoside-triphosphate:oxidized-thioredoxin 2'-oxidoreductase），系統名「2-2'-脫氧核糖核苷三磷酸：硫氧還蛋白二硫鍵-2'-氧化還原酶」（2'-deoxyribonucleoside-triphosphate:thioredoxin-disulfide 2'-oxidoreductase）[1][2][3]，係一種能催化以下化學反應的酶：
2'-脫氧核糖核苷三磷酸+硫氧化還原蛋白二硫鍵+H2O 核糖核苷三磷酸+硫氧化還原蛋白
核苷三磷酸還原酶的作用需要cobamide輔酶，同時還要消耗ATP。
