Alekhin is a lunar crater that is located on the southern hemisphere on the far side of the Moon. It lies to the north of the Zeeman crater, and south-southeast of Fizeau crater. To the west lies the Crommelin crater, and east-southeast is the Doerfel crater.
The rim of Alekhin has been heavily eroded by subsequent impacts to the point where the edge is little more than a curving rise in the surface. The outer wall is completely overlain by the crater pair formed by crater Dawson across the northwest rim and 'Dawson D' on the northern rim. The southern rim is somewhat more heavily marked by gouges and irregularities in the surface, compared to the northeast rim. On the floor are a number of tiny craterlets.

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 Alekhin crater.
