Percy Cudlipp (10 November 1905 – 5 November 1962), was a prominent Welsh journalist.
He was born at 180 Arabella Street, Cardiff, and was the brother of Hugh Cudlipp (later Baron Cudlipp) and Reginald Cudlipp, both notable journalists. Percy Cudlipp began his journalistic career with the South Wales Echo. He became editor of the Evening Standard in 1933 and of the Daily Herald in 1940, and was at one time the youngest editor in Fleet Street.
In 1953, Cudlipp resigned the editorship of the Daily Herald. Shortly afterwards, he was approached by the team setting up the New Scientist and became the first editor of the new magazine in 1956. He died at his home, 11 Falmouth House, Clarendon Place, London.
