The Chahamanas of Ranastambhapura were a 13th-century Indian dynasty. They ruled the area around their capital Ranastambhapura (Ranthambore) in present-day Rajasthan, initially as vassals of the Delhi Sultanate, and later as sovereigns. They belonged to the Chahamana (Chauhan) clan, and are also known as Chauhans of Ranthambore in vernacular Rajasthani bardic literature.
