Atwood is a small lunar impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim. All three were satellite craters of Langrenus before being renamed by the IAU. (Atwood was formerly designated Langrenus K).

Atwood lies near the edge of the outer ramparts of Langrenus, and the ejecta forms low ridges attached to the south rim of Atwood. Within the crater interior is a low central peak that joins a ridge line to the north rim of the crater.
