William Shaw (died 15 May 1937) was a Scottish trade unionist and politician. Born in Stranraer, Shaw worked as a joiner and became involved with the Amalgamated Society of Carpenters and Joiners early in life. In 1916, he was elected unopposed as the secretary of Glasgow Trades Council, at the time also the Labour Party organisation for the city. At the time, he was active in the Independent Labour Party and was an opponent of World War I. This enabled him to have a reasonable working relationship with the Clyde Workers' Committee, and he wrote to the British Socialist Party asking them to support the committee's strike.
