Uranius Tholus is a volcano on Mars located in the Tharsis quadrangle at 26.52° north latitude and 262.43° east longitude. It is 61.4 kilometres (38 mi) across with an elevation of 4,290 metres (14,075 ft)[1] and was named after a classical albedo feature name.[2]

Uranius Tholus is part of the Uranius group of volcanoes and lies north of the larger Ceraunius Tholus.


Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano. "Mons" is a term used for a large raised feature. "Tholus" is about the same, but smaller.
