Magelhaens is an impact crater in the southern time of Mars, located at 32.36° south latitude and 185.42° east longitude, in the Phaethontis quadrangle. Its diameter is 105 km. Its name refers to Ferdinand Magellan, the 16th century Portuguese explorer.
Magelhaens is located southwest of the volcanic region of Tharsis. It is surrounded by rocky peaks of unknown origin. These forms may be the result of tectonic movements in the Tharsis region, or of meteorite impacts.
