Theia Mons is a large highland shield volcano on the planet Venus. Located near the center of Beta Regio, a large region of recent volcanic uplift due to a currently active mantle plume, Theia Mons is situated at the junction of three branches of Devana Chasma, an extensive rift system. It is named after Theia, a Titan from Greek mythology; the name Theia Mons was officially approved by the International Astronomical Union (IAU) in 1979.
