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 Lemaître crater. To the south-southwest is Crommelin crater, and to the northeast is Fizeau crater.
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. The inner walls display some minor terracing along the northwestern edge. Near the mid-point of the crater interior floor is a horseshoe-shaped central peak formation, with the open end pointing toward the south.

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Eijkman crater.
