Alwar State is a princely state of Naruka Rajputs with its capital at Alwar in India. Founded in 1770 CE by Pratap Singh Naruka, its reigning ruler, Maharaja Sir Tej Singh Prabhakar Bahadur, signed the accession to the Indian Union on 7 April 1949.

Alwar State was established in 1770,by a Kachwaha Rajput named Pratap Singh Naruka.

Following the Partition of India in 1947, Alwar acceded unto the dominion of India with the state's forces participating in and encouraging the killings and expulsion of its Hindu population. On 18 March 1948, the state merged with three neighbouring princely states (Bharatpur, Dholpur and Karauli) to form the Matsya Union. This union in turn merged unto the Union of India. On 15 May 1949, it was united with certain other princely states and the territory of Ajmer to form the present-day Indian state of Rajasthan.
