In human anatomy, the inguinal triangle is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle, after Franz Kaspar Hesselbach.

It is defined by the following structures:

This can be remembered by the mnemonic RIP (Rectus sheath (lateral border), Inferior epigastric artery, Poupart's ligament (inguinal ligament)).
