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 (medial), Inferior epigastric artery (lateral), Poupart's ligament (inguinal ligament, inferior).

The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.
