Turtle Mountain was a provincial electoral division in the Canadian province of Manitoba. It was created with the westward expansion of the province's boundaries in 1881, eliminated by redistribution in 1968, and re-established in 1979, formally returned to the electoral map with the provincial election of 1981. It was dissolved for the 2011 election.

The riding was primarily rural. Communities in the riding included Killarney, Carberry, Glenboro, Pilot Mound and MacGregor.
The riding's population in 1996 was 18,569. In 1999, the average family income was $43,265, and the unemployment rate was 3.50%. Agriculture accounted for 37% of all industry in the riding, followed by health and social service work at 9%. Thirteen per cent of the riding's residents were German.
Turtle Mountain was represented by the Progressive Conservative Party for most of its history, and was considered safe for that party.
