William Templeman, PC (September 28, 1844[1] – December 15, 1914) was a Canadian newspaper editor and politician.

Born in Pakenham, Canada West, he was managing editor and owner of the Victoria Daily Times (now part of the Victoria Times-Colonist) newspaper, before first running as the Liberal candidate for the House of Commons of Canada for the riding of Victoria in the 1891 election.

He was appointed to the Senate of Canada in 1897 representing the senatorial division of New Westminster, British Columbia.

He resigned from the Senate in 1906 to run in the riding of Victoria City when the current MP, George Riley (who was soon after appointed to the Senate), resigned to allow him to run.

He was defeated again in the 1911 federal election in the riding of Victoria City.
