Moss Turner-Samuels (19 October 1888 – 6 June 1957) was a Labour Party politician in the United Kingdom. He was elected to the House of Commons at the 1923 general election as Member of Parliament (MP) for the Barnard Castle constituency, but lost his seat the following year in the 1924 election to the Conservative candidate, Cuthbert Headlam. He was returned to Parliament twenty years later, in the Labour landslide at the 1945 general election, defeating the long-serving Conservative Leslie Boyce in Gloucester. He was re-elected at the next three general elections, but died in office at Westminster in 1957, aged 68. At the subsequent by-election, his seat was retained for Labour by Jack Diamond.
