D'Arrest is a lunar crater that is located in the lava-flooded region to the west of the Mare Tranquillitatis. It lies to the southeast of Agrippa crater and northwest of Delambre crater. Just to the northeast are the small, bowl-shaped De Morgan and Cayley craters.
The outer rim of d'Arrest is broken in several places, with a gash at the south end and a wide gap to the northeast where only a low ridge remains in place of the original wall. The interior has been resurfaced by lava, leaving a nearly flat, featureless floor. The surviving rim is low and worn, with ridges connecting it to the south and southwest.

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 d'Arrest crater.
