Dante is a lunar crater on the far side. It lies in the northern hemisphere exactly opposite the prime meridian facing the Earth. The nearest craters of note are Larmor to the north and Morse to the southeast. To the southwest is the oddly shaped Buys-Ballot. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
