Moulton is a crater on the Moon's far side, just beyond the south-southwestern limb as seen from the Earth.

The crater is attached to the southern edge of Chamberlin, and it lies at the northern terminus of the Vallis Schrödinger.

Attached to the eastern outer rim is the satellite crater Moulton H. The interior floor has been resurfaced, although the albedo is not as low as the lava-flooded interior of Chamberlin.

There are no craters of note on Moulton's rim or within the interior.

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