Wiener is a lunar impact crater that lies on the Moon's far side from the Earth. It is located just to the southwest of the larger Campbell crater. To the southwest of Wiener is the heavily worn Kurchatov crater. To the east along the rim of Campbell is the Von Neumann. The smaller Pawsey crater lies to the north-northwest, and is partly overlaid by the outer rampart of Wiener.

The northwestern half of the crater rim is well-formed, with some slumping and terraces along the inner walls. There is an outward protrusion in the rim along the northern side where the crater borders along Pawsey. The southern part of the crater is more irregular, with a wider, uneven inner wall and a poorly-defined rim edge. The rim overlays about half of the heavily worn satellite crater 'Wiener K' along the south-southeast. The smaller satellite crater 'Wiener Q' lies along the southwestern rim, and the relatively fresh and polygon-shaped 'Wiener F' is attached to the eastern rim.

Within the crater, much of the interior floor is relatively level, with a clump of small ridges forming a central peak structure near the mid-point. There is a small craterlet to the east-northeast of these ridges, and there are several small craterlets near the southwestern 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 Wiener crater.
