Webb is a small lunar impact crater that is located near the eastern edge of the Mare Fecunditatis, in the eastern part of the Moon near the equator. It is to the north of the prominent crater Langrenus, and west of Maclaurin.

The interior of Webb is relatively dark compared with the inner walls of the rim, and it has a low hill at the midpoint of the interior. On the lunar mare to the north is a faint marking of a ray system that appears to radiate from this crater.

It is named for British astronomer Thomas William Webb.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Webb.
