The arcuate line of the ilium is a smooth rounded border on the internal surface of the ilium. It is immediately inferior to the iliac fossa and Iliacus muscle.

It runs inferior, anterior, and medial.

It forms part of the border of the pelvic inlet.

In combination with the pectineal line, it comprises the iliopectineal line.^[1]
