Van Wijk is a small lunar impact crater located in the southern part of the far side of the Moon. It lies to the north-northwest of the huge walled plain Schrödinger, and to the southwest of the crater Fechner.
The rim of this crater has a noticeable outward bulge toward the south, but it remains relatively circular overall. The perimeter is mostly sharp-edged, with some wear along the north and northwest faces. The inner walls slope down evenly towards the relatively flat and featureless interior of the crater.
