McNair is a small lunarimpact crater on the far side of the Moon. It lies within the double-ringed Apollo basin, inside the eastern part of the interior ring. It has partly merged with the crater Jarvis, and the two share a common rim. To the south of McNair lies Borman.
This is a bowl-shaped feature with a somewhat worn outer rim. There are some tiny craterlets along the southern rim, and a narrow cut through the edge to the south-southwest. The interior floor is relatively featureless.
