John Roundell Palmer, 4th Earl of Selborne (24 March 1940 – 12 February 2021) was a British peer, ecological expert, and businessman.

[2] The son of Captain William Palmer, Viscount Wolmer (in turn son of Roundell Palmer, 3rd Earl of Selborne, and the Honourable Grace Ridley), and Priscilla Egerton-Warburton, Lord Selborne succeeded to his grandfather's titles in 1971;[3] this was because his father had been killed in 1942 during a training exercise while serving with the Hampshire Regiment.

Lord Selborne was treasurer of King Edward's School, Witley, between 1972 and 1983, and a member of the Apple and Pear Development Council between 1969 and 1973.

He was chairman of the Hops Marketing Board from 1978 to 1982, of the Agricultural and Food Research Council (AFRC) from 1982 to 1989, and of the Joint Nature Conservation Committee (JNCC) from 1991 to 1997.
