Maurolycus is one of the more prominent lunar impact craters in the southern highland region of the Moon that is covered in overlapping crater impacts. It was named after 16th century Italian mathematician Francesco Maurolico. It is joined at the southeast rim by the smaller crater Barocius. Due west lie the overlapping pair of Stöfler and Faraday. To the northeast is the faint crater Buch, and further to the north lies Gemma Frisius.
