Avery is a small lunar impact crater located near the eastern limb of the Moon.[4] It has an estimated age of ~150 ma, which puts it in the Copernican period of the lunar geologic timescale.[3] This is a circular, bowl-shaped formation with a small interior floor at the center. It is 10.7 km[1] in diameter with walls that slope down to a depth of 2,170 m.[2] This crater lies near the western edge of Mare Smythii. To the east is the crater Haldane, and to the southwest is Carrillo. Gilbert lies to the southwest.[5]

Avery was previously designated as satellite feature Gilbert U,[6] before its name was formally adopted by the IAU in 1976. It is named after the Canadian-American biomedical researcher Oswald Avery (1877-1955).[1]
