Coningsby Ralph Disraeli (25 February 1867 – 30 September 1936), was a British Conservative politician.
Born in Kensington, London, Disraeli was the son of Ralph Disraeli (1809–1898, the younger son of the writer Isaac D'Israeli). He was educated at Charterhouse School and New College, Oxford. The Prime Minister Benjamin Disraeli was his uncle. He inherited the Hughenden Manor estate acquired by his uncle on his father's death in 1898.
Disraeli was an officer in the Buckinghamshire Yeomanry, where he was commissioned a Second lieutenant on 18 April 1900, and promoted to Lieutenant on 11 June 1902.
He entered Parliament for Altrincham in the 1892 general election, a seat he held until 1906 when he was defeated in the general election of that year.
Disraeli died in Hove, East Sussex in September 1936, aged 69.
