Townley is a small lunar impact crater that is located in the eastern part of the Moon.

It was named after American astronomer Sidney Dean Townley in 1976.

[2] It lies to the northwest of Mare Spumans and southeast of the crater Apollonius.

This crater was previously designated Apollonius G. This crater is generally circular, with inner wall that slopes down to a relatively dark floor that is generally flat.

The albedo of this floor is similar to the lunar mare to the southeast.
