Maskelyne is a solitary lunar crater that lies in the southeast part of the Mare Tranquillitatis. The outer rim has a somewhat polygonal shape, although it is generally circular. The inner walls are terraced and there is a low central rise at the midpoint of the floor.

The landing site of the Apollo 11 expedition is located about 250 kilometers to the west-southwest. To the northeast are Wallach and Aryabhata. To the southeast is the bright Censorinus. To the south are the lunar mountains informally known as Duke Island and Boot Hill.

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