The '''external [[ilium (bone)|iliac]] [[artery]]''' is a large artery in the pelvic region that carries blood to the [[lower limb]].
The external iliac artery is a paired artery, meaning there is one on each side of the body: a ''right external iliac artery'' and ''left external iliac artery''.
The external iliac artery is accompanied by the [[external iliac vein]], which is located posterior to the artery.

The external iliac artery arises from the bifurcation of the [[common iliac artery]]. It travels inferiorly, anteriorly, and laterally, making its ways to the lower limb:
==Branches==
{| class="wikitable"
| '''Branch''' || '''Description'''
|-
| [[Inferior epigastric artery]] || Goes upward to anastomose with [[superior epigastric artery]] (a branch of [[internal thoracic artery]]).
|-
| [[Deep circumflex iliac artery]]|| Goes laterally, travelling along the iliac crest of the [[pelvic bone]].
|-
| [[femoral artery]] || Terminal branch. When the external iliac artery passes posterior to the [[inguinal ligament]], its name changes to [[femoral artery]].
