Diameter	54 km

Colongitude	144° at sunrise
Eponym	Christiaan Eijkman

Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.

The rim of this crater is well-defined and has not been significantly worn down by impacts. Nevertheless, there are a few tiny craterlets along the edge and a small craterlet along the northern inner wall.^[1] The inner walls display some minor terracing along the northwestern edge. Near the midpoint of the crater interior floor is a horseshoe-shaped central peak formation, with the open end pointing towards the south.
