Thomas Glassey (26 February 1844 – 28 September 1936) was an Irish-born Australian politician. Born in Markethill, County Armagh, he received no formal education, working as a mill-worker and miner in Scotland and England. He migrated to Australia around 1885, when he became a miner at Bundamba, and was Secretary of the Bundamba Miners Association. He was a founding member of the Australian Labor Party in Queensland, and was the first Labor member of any Australian parliament when he was elected to the Legislative Assembly of Queensland in 1888 as the member for Bundamba.
