Hess is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon.

The crater rim has been worn by subsequent impacts, leaving a low, eroded outer wall.

The crater Boyle is nearly attached to the northeastern rim of Hess, and Abbe lies to the south.

To the west is the large walled plain Poincaré, and Hess is located at the eastern edge of the crater's deeply eroded outer rim.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hess.
