细胞色素 P450 27B1（英语：Cytochrome P450 27B1，缩写CYP27B1）也被称为25-羟基维生素 D3 1-α-羟化酶（25-Hydroxyvitamin D3 1-alpha-hydroxylase,化学式为：C2567H4025O707N739S16Fe[1]，EC 1.14.15.18），是细胞色素P450超家族的一员，由CYP27B1基因编码，定位于线粒体内膜[2][3][4]，在许多组织细胞中表达，如肾的近曲小管、皮肤角质形成细胞、免疫细胞[5]、成骨细胞等[6]，催化骨化二醇羟基化生成骨化三醇（维生素D的活性形式）[7]：
- 骨化二醇 + 2 还原型 Adx + 2 H+ + O2 ⇌ 骨化三醇 + 2 氧化型 Adx + H2O
