Landau is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon.

The outer rim of Landau is heavily eroded and modified by subsequent impacts.

Prior to formal naming by the IAU in 1970,[1] Landau was called Crater 97.

[2] Landau lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age.

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