Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere.

Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.

There is a small but prominent crater lying across the southwest rim, with an inner surface that forms terraced steps covering most of the interior.

The interior of Fizeau is relatively flat beyond the terraces, with only a few low rises in the northwest section of the crater and a central peak near the midpoint.

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