Thomas Scott (1 January 1842 – 4 March 1870) was an Irish Protestant who emigrated to Canada in 1863.
While working as a labourer on the "Dawson Road Project", he moved on to Winnipeg where he met John Christian Schultz and fell under the influence of the Canadian Party.
His political involvement in the Red River Settlement from then on led to his capture at Fort Garry where he was held hostage with others.
