Census Division No. 15 (Western Manitoba) is a census division located within the Westman Region of the province of Manitoba, Canada.

The economy of the region is based on agriculture, livestock and hog processing. The population of the area based on the 2006 census was 21,417. Also included in the division are the main reserves of the Birdtail Sioux First Nation, the Keeseekoowenin Ojibway First Nation, and the Rolling River First Nation.
