Carmichael is a lunar impact crater that is located along the eastern edge of the mare surface named Sinus Amoris, in the northeastern quadrant of the Moon's near side.[3] Its diameter is 20 km.[1] Carmichael lies within a couple of crater diameters south-southwest of the smaller crater Hill. Further to the east-northeast is the prominent crater Macrobius.[3]

Carmichael is generally circular, with a small floor at the middle of the sloping interior walls. There is a low rise of scree along the southeast inner wall. The crater is free of notable impacts along the rim or the interior, although a tiny craterlet is situated in the lunar mare just outside the rim to the south-southwest.[4]

Previously identified as satellite feature Macrobius A, this crater is named after American psychologist Leonard Carmichael (1898-1973). Its designation was officially adopted by the International Astronomical Union in 1973.[1]
