Simpelius is an impact crater that lies in the southern part of the Moon. It lies to the north-northwest of the somewhat larger crater Schomberger, and east-southeast of the prominent Moretus.

The most distinctive aspect of this crater is the asymmetry of the inner wall, with the side being nearly twice as wide at the southern end as it is to the north. As a result, the level interior floor is offset to the north of the crater interior. The rim and inner wall are less sharply defined than those of Schomberger or Moretus, having been softened and smoothed by impacts. The rim is uneven, with peaks to the north, west, east, and south-southeast, and low sections in between. There are also a number of small crater pits along the inner wall and the interior floor.
India's Chandrayaan-3 mission successfully landed near the crater at 69.37 degrees south latitude and 32.35 degrees east longitude.
