The deep artery of the penis (artery to the corpus cavernosum) is a small collateral branch of the internal pudendal artery that supplies the corpus cavernosum. The artery enters the crus of penis at the crus' anterior extremity.

The deep artery of the penis one of the terminal branches of the internal pudendal artery.^{[citation needed]} It arises from the internal pudendal artery posterior to the inferior edge of the symphysis pubis while the internal pudendal artery is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch).^{[citation needed]}

It traverses the pelvic floor, then immediately enters the corpus cavernosum penis. It runs anterior-ward in the center of the corpus cavernosum penis, to which its branches are distributed.^{[citation needed]}

In the center of the corpus cavernosum, it splits into an anterior branch (which supplies the anterior two-thirds of the corpus cavernosum), and a recurrent branch (which supplies the posterior one third of the corpus cavernosum).
