Tharosaurus (meaning "Thar Desert lizard") is an extinct genus of potentially dubious eusauropod sauropod dinosaurs from the Middle Jurassic Jaisalmer Formation of India. The genus contains a single species, Tharosaurus indicus, known from a fragmentary skeleton including several vertebrae and a rib. When it was named in 2023, Tharosaurus was interpreted as the earliest known diplodocoid and the first member of this clade described from India. However, a later revision of the fossil material argued for a position outside of this clade, as an indeterminate eusauropod. This revision could not find unique features in the Tharosaurus specimen, so it was classified as a nomen dubium.
