Licetus is a lunar impact crater on the near side of the Moon, in the rugged southern highland region.

It lies to the south of the walled plain Stöfler, and is attached to the northern rim of the sub-divided crater Heraclitus.

The interior floor is relatively flat, with some minor ridges and slips in the southern half.

[2] The crater is named after Fortunio Liceti, a 17th-century Italian philosopher and physicist.

[1] By convention, these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Licetus.
