Hammiradeva was the last ruler from the Ranthambore branch of the Chauhans (Chahamanas). He is also known as Hamir Dev Chauhan in the Muslim chronicles and the vernacular literature.

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 gained independence. They belonged to the Chahamana (Chauhan) clan of the Rajputs, and are also known as Chauhans of Ranthambore in vernacular Rajasthani bardic literature.
