Provincial Road 426 (PR 426) is a 6.5-kilometre-long (4.0 mi) north–south highway in the Pembina Valley Region of Manitoba.

Located entirely in the Rural Municipality of Montcalm, it connects PTH 14 with the hamlet of St. Joseph and PR 201.

Leaving St. Joseph, the asphalt transitions to gravel as the highway travels due north through rural farmland for the next several kilometres to come to an end at an intersection with PTH 14, with the road continuing north as Road 3E.

[3][4][5][6] Between 1966 and 1992, PR 426 existed as a 25.3-mile-long (40.7 km) gravel highway in the Central Plains Region, running from PTH 1 (Trans-Canada Highway/Yellowhead Highway) on the northern edge of Bénard to PR 430 just south of Poplar Point.

It provided access to the Hutterite colonies of Huron and Polpar Point and another access to St. Eustache, while its most prominent feature was its section along River Road, where it followed the south bank of the Assiniboine River.
