Richard William Marsh, Baron Marsh PC (14 March 1928 – 29 July 2011) was an English politician and business executive.
The son of William Marsh, a foundry worker from Belvedere in southeast London. His father subsequently worked for the Great Western Railway, and the family moved to Swindon. He was educated at Jennings Street Secondary School, Swindon, Woolwich Polytechnic and Ruskin College, Oxford. He initially worked as an official for the National Union of Public Employees from 1951 to 1959, during which time he sat on the Clerical and Administrative Whitley Council for the National Health Service.
After unsuccessfully standing at Hertford in 1951, Marsh was elected as Labour Party Member of Parliament (MP) for Greenwich at the 1959 general election.
As a backbencher he submitted a private members bill in 1960 which despite Government opposition became the Offices, Shops and Railway Premises Act, a white-collar equivalent of the Factories Act and the forerunner of the Health and Safety at Work Act.
