Werner is a prominent lunar impact crater that lies in the rugged south-central highlands of the Moon. It is almost joined with Aliacensis crater to the southeast, and the pair form a rugged valley in the intervening gap. Due west of Werner is the distorted Regiomontanus crater, and to the north is the remains of the Blanchinus crater.
The rim of Werner crater shows little appearance of wear, and is much younger and less eroded that the other large craters in the surroundings. The interior wall is terraced, and there is a noticeable rampart on the exterior. There are several low rises on the crater floor and a notable central peak. Rev. T. W. Webb noted two very bright spots along the sides of this crater, more visible in larger aperature telescopes. The Clementine Lunar Atlas displays a patch of high albedo surface along the northern inner wall.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Werner crater.
