Thomas Miller (July 21, 1876 – June 20, 1945) was the shortest serving and seventh lieutenant governor of Saskatchewan in 1945 for less than four months.

While he was a boy, his family moved to Regina, Saskatchewan.

When the proprietors purchased the Moose Jaw Times they put Miller in charge of the printing press.

He was appointed lieutenant-governor in 1945 on the advice of federal Prime Minister William Lyon Mackenzie King and made his official residence at the Hotel Saskatchewan as the provincial government had closed Government House the previous year.

Miller presided over victory celebrations in the province following the end of World War II.
