Sir Noel Hughes Havelock Charles, 3rd Baronet, KCMG, MC (20 November 1891 – 8 September 1975) was a British diplomat.

Charles was the younger son of Sir Havelock Charles, 1st Baronet, Serjeant Surgeon to King George V. Educated at Rugby School and Christ Church, Oxford, he served in the First World War in France, receiving the Military Cross^[1] and two mentions in despatches.

Charles was appointed British Ambassador to Brazil in 1941.^[2] In 1944, he was sent to Rome as British High Commissioner in Italy (subsequently Representative of HM Government to the Italian Government, with personal rank of Ambassador), serving there until 1947. While in Rome, he sent a memo to the British government suggesting that they urge Italy to set up a system of issuing exit permits to prevent Italy being used as a pathway for Jews seeking to reach Israel. Noel's Rome home was extensively damaged during a 1946 bombing by Irgun terrorists; he and his wife were away that day.^[3][4] After serving in London from 1947 to 1949, he retired in 1951.
