Newcomb is a lunar impact crater that is located in the rugged Montes Taurus mountain range, to the east of the Mare Serenitatis. It lies to the northeast of the prominent Römer crater, and north-northwest of Macrobius crater.
This crater has a sharp-edged and somewhat irregular rim that appears polygonal more than circular. There are terraces along the inned sides, with some slumping along the northern and western inner edge. The south-southwestern part of the rim is overlaid by the smaller crater 'Newcomb A'. The interior floor is uneven, particularly near the rim of 'Newcomb A'. Just to the south-southeast of the crater is the satellite crater 'Newcomb J'.
This feature is named after the American astronomer Simon Newcomb.

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 Newcomb crater.
