Thomas Urquhart (April 16, 1858 – February 16, 1931) was a Canadian politician who served as mayor of Toronto from 1903 to 1905.

His parents were Sarah McCallum and Alexander Cameron Urquhart, a pioneer tailor and storekeeper who immigrated from Dingwall, Ross and Cromarty, Scotland to Canada in 1847.

After becoming ill at his office, Urquhart was taken to his home at 136 Hillsdale Avenue in Toronto, where he died on February 16, 1931, from influenza.
