| Eponym | Democritus |
Democritus is a lunar impact crater that is located on the northern part of the Moon, just to the north of the Mare Frigoris. Just to the south of Democritus is the lava-flooded Gärtner crater, which forms a bay on the mare. Directly to the north is Arnold crater, another flooded formation.
The rim of Democritus is generally sharp-edged and shows little sign of erosion. It forms not quite a circle, with outward notch-like bulges that give it a slightly irregular shape. The inner walls have single or double terraces that lead down to a relatively flat interior floor. Near the mid-point of the crater is a small central peak.

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 Democritus crater.
