Rampur State was a 15 gun-salute princely state of British India. It came into existence on 7 October 1774 as a result of a treaty with Oudh. Following independence in 1947, Rampur State and other princely states of the area, such as Benares and Tehri Garhwal were merged into the United Provinces. Rampur state had its capital in Rampur city and its total area was 945 sq miles. Rampur state was founded by Ali Mohammad Khan's younger son Faizullah Khan.

A salute state was a princely state under the British Raj that had been granted a gun salute by the British Crown ; i.e., the protocolary privilege for its ruler to be greeted—originally by Royal Navy ships, later also on land—with a number of cannon shots, in graduations of two salutes from three to 21, as recognition of the state's relative status. The gun-salute system of recognition was first instituted during the time of the East India Company in the late 18th century and was continued under direct Crown rule from 1858.
