Dauphin is a former provincial electoral division in the Canadian province of Manitoba. It was created in 1881 with the expansion of the province's western boundary, eliminated in 1886, re-established in 1892, and finally abolished in 1999. Most of its territory went to the new riding of Dauphin-Roblin, though a small amount went to the riding of Swan River.

Dauphin was initially centred around the community of Dauphin, Manitoba, though it eventually became known as a rural constituency. It was located in the province's mid-northern region, close to the provincial border with Saskatchewan.
