内阴动脉（Arteria pudenda interna）源自于内髂动脉，为三条阴部动脉的其中一条。内阴动脉负责供养外生殖器的血流。
内阴动脉为内髂动脉前分支的终末分支，在雌性个体身上较雄性细小。
解剖
内阴动脉源自于内髂动脉，并爬经骨盆侧壁。并于坐骨大孔的梨形肌下方离开骨盆腔，进入臀部。之后沿着荐棘韧带，穿过坐骨小孔进入会阴。后与内阴静脉及阴部神经在会阴管中并行。
分支
内阴动脉拥有以下分支：
| 女性 | 男性 | 描述 |
| 下直肠动脉 | 下直肠动脉 | 供应肛管 |
| 会阴动脉 | 会阴动脉 | 供应会阴浅横肌 |
| 阴唇后支 | 阴囊后动脉 | - |
| 前庭球动脉 | 阴茎球动脉 | 供应前庭球及阴茎球 |
| 阴蒂背动脉 | 阴茎背动脉 | - |
| 阴蒂深动脉 | 阴茎深动脉 | 至阴茎海绵体 |
