The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis. They proceed anterior and inferior along the medial border of the psoas major muscles. They exit the pelvic girdle posterior and inferior to the inguinal ligament about 1/3rd laterally from the insertion point of the inguinal ligament on the pubic symphysis at which point they are referred to as the femoral arteries.Tortora, Gerard J.; Grabowski, Sandra R.

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
| 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. |
