John Cyril Maude KC (3 April 1901 – 16 August 1986) was a British barrister and Conservative Party politician. He sat in the House of Commons from 1945 to 1951, and then became a judge.
Maude was the son of the actors Cyril Maude and Winifred Emery. He was educated at Eton College and Christ Church, Oxford, and was called to the bar in 1925 at the Middle Temple.
He was the Recorder of Devizes from 1939 to 1944, and of Plymouth from 1944 to 1954. He became a King's Counsel in 1943, and a bencher in 1951. He was Counsel to the Post Office at the Central Criminal Court from 1935 to 1942, and junior counsel to the Treasury from 1942 to 1942.
During the Second World War, he served as a temporary Civil Assistant at the War Office in 1939. In 1940 he joined the Military Intelligence Corps with the rank of Major, and worked in the offices of the War Cabinet in 1942.
He was elected at the 1945 general election as the Member of Parliament (MP) for Exeter. Having been selected as a candidate, he found that the election campaign clashed with his duties in a libel case at the High Court, but his application to postpone the cases was refused by Justice Cassels.
