Thomas MacPartlin

Thomas MacPartlin (22 August 1879 – 20 October 1923) was an Irish Labour Party politician. He was a member of Seanad Éireann from 1922 to 1923.

A trade union official from County Sligo, he was a member of the Amalgamated Society of Carpenters and Joiners union and served as the president of the Irish Trades Union Congress (ITUC) in 1917. He was a signatory of the 1914 ITUC manifesto opposing inclusion of a partition option in the draft home rule bill and asserting workers' right to arm and fight for 'economic freedom'. He was elected to the Free State Seanad for 9 years at the 1922 election.

He died in office in October 1923, while on a visit to Geneva. The by-election to fill the vacancy was held on 28 November 1923, and was won by Thomas Foran of the Labour Party.
