Bolyai is an old lunar crater that is located in the southern hemisphere on the far side of the Moon. To the southeast of Bolyai is the crater Eötvös and to the north is Neujmin.This crater has been heavily eroded and worn by subsequent impacts leaving only a deformed remnant of the original rim that is overlaid by a multitude of lesser craters. The most notable of these is Bolyai D along the northeast rim and Bolyai W to the northwest.
