在人体解剖学中,下腹壁动脉(Arteria epigastrica inferior)指的是外髂动脉(英语:external iliac artery)和上腹壁动脉的动脉吻合。与其伴行的有同名静脉下腹壁静脉(英语:inferior epigastric vein)。
下腹壁动脉源自于外髂动脉,比腹股沟韧带稍微上方一些的地方。
下腹壁动脉会在腹膜下的结缔组织中微微向前行走,后沿腹股沟环的内缘上行一小段后继续上行,钻入横筋膜(英语:transversalis fascia)之间,并经过腹弓状线(英语:linea semicircularis)前方,于腹直肌和后方筋膜之间上行。
下腹壁动脉会形成数个分支,并会在肚脐上方与上胸动脉、上腹壁动脉,以及最下肋间动脉(英语:lower intercostal arteries)形成动脉吻合。
