Tausonite is the rare naturally occurring mineral form of strontium titanate: chemical formula: SrTiO3. It occurs as red to orange brown cubic crystals and crystal masses.

It is a member of the perovskite group.

It was first described in 1982 for an occurrence in a syenite intrusive in Tausonite Hill, Murun Massif, Olyokma-Chara Plateau, Sakha Republic, Yakutia, geologically part of the Aldan Shield, Eastern-Siberian Region, Russia.[2] It was named for Russian geochemist Lev Vladimirovich Tauson (1917–1989).[4] It has also been reported from a fenite dike associated with a carbonatite complex in Sarambi, Concepción Department, Paraguay.[3] and in high pressure metamorphic rocks along the Kotaki River area of Honshu Island, Japan.[2]
