James Moffat Douglas (May 26, 1839 – August 19, 1920) was a farmer, missionary, and politician in western Canada. He served as a Member of Parliament (MP) for a district in the Northwest Territories from 1896 to 1904 and as a Canadian Senator from 1906 until his death in 1920. Born to John and Euphemia (Moffat) Douglas, he received his early education in Linton, Roxburghshire, Scotland, before immigrating with his family to a small farm near Cambray, Ontario, in 1851. Douglas was elected to the House of Commons in 1896 for the district of Assiniboia East, defeating William McDonald. He was supported by the Liberal Party and local farmers' organization, the Patrons of Industry. Re-elected in 1900, he retired from the House in 1904. On March 8, 1906, Douglas was appointed to the Canadian Senate to represent Saskatchewan on the recommendation of Prime Minister Wilfrid Laurier. He served as an Independent Liberal until his death in 1920. In 1904, Douglas built a homestead in the Qu'Appelle Valley, naming it Tantallon after Tantallon Castle in Scotland, which inspired the village’s name.
