Wilsing is a lunar impact crater on the far side of the Moon.

Wilsing is located just inside the rim of the immense South Pole-Aitken basin.

This is a heavily worn formation with the smaller satellite crater Wilsing Z lying prominently across the northern half of the interior floor.

The interior floor is somewhat uneven, with the most level portion being in the south-southwest.

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