Fernelius is a lunar impact crater located in the southern highlands just to the north of the walled plain Stöfler. The crater Kaiser is located next to the northwest rim of Fernelius. To the north-northwest are the craters Nonius and Walther. Southeast of Fernelius is the crater cluster of Miller, Nasireddin, Huggins, and Orontius.

In the past the floor of Fernelius has been resurfaced, leaving a relatively flat, featureless surface with no central peaks. The crater rim has been heavily worn and indented by impacts, the most prominent being Fernelius A which intrudes into the western rim.
