Reid Anthony Railton (25 June 1895 – 1 September 1977) was a British automotive engineer, and designer of land and water speed record vehicles.

Reid Anthony Railton was the son of a Manchester stockbroker: Charles Withingon Railton and his wife Charlotte Elizabeth (née Sharman), Reid was born in Chorley, Alderley Edge, Cheshire and was christened on 13 August 1895 at the local parish church.

He left in 1922 to set up the Arab Motor Company where he was chief designer.

In 1927, on the death of his friend Parry-Thomas, Railton closed the Arab factory and moved to Brooklands working for Thomson & Taylor becoming their Technical Director with responsibility for John Cobb's 1933 Napier Railton car which took the Outer Circuit record in 1933 and Sir Malcolm Campbell's Blue Bird Land Speed Record cars of 1931 to 1935.

As well as cars he designed high-speed boats, including the jet-powered Crusader in which John Cobb was killed in 1952 while travelling in excess of 200 mph (322 km/h) attempting to break the Water Speed Record.
