Dirichlet is a lunar impact crater that is located on the Moon's far side. It is attached to the southern outer rim of the crater Henyey. To the south-southeast is the much larger crater Tsander.

This is a circular crater with a sharp-edged rim that is not significantly worn. There are slight outward protrusions along the eastern side. The sides of the inner walls have slumped down to form a ring of scree along the base.

Dirichlet lies on the eastern margin of the Dirichlet-Jackson Basin.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Dirichlet.
