Sir Cuthbert Morley Headlam, 1st Baronet DSO, OBE, TD, DL (27 April 1876 – 27 February 1964) was a British Conservative politician.
Born in Barton upon Irwell, Lancashire, Headlam was educated at King's School, Canterbury, and at Magdalen College, Oxford. He was a Clerk in the House of Lords 1897–1924 and became a barrister, Inner Temple in 1906. He served with the Bedfordshire Yeomanry from 1910–1926, was mentioned in despatches in the First World War and awarded the Distinguished Service Order and appointed an Officer of the Order of the British Empire, retiring as lieutenant colonel.
Headlam was elected as Member of Parliament (MP) for Barnard Castle at the 1924 general election. After the loss of his seat in 1929, he stood in the Gateshead by-election in June 1931, coming a close second in what had been a safe seat for Labour. He regained the Barnard Castle seat at the general election in October 1931, but was defeated again at the 1935 general election. He was returned to the House of Commons for a third time at a by-election in June 1940 as MP for Newcastle upon Tyne North, after standing as an "Independent Conservative" and beating the official Conservative Party candidate. He held the seat until he retired from Parliament at the 1951 general election.
