Provincial Road 254 (PR 254) is a 118.7-kilometre-long (73.8 mi) north–south highway in the Westman Region of Manitoba.

It heads north as an unpaved gravel road, going through a switchback before travelling through Medora along Third Street, where it crosses a small creek, a railroad, and has a short concurrency (overlap) with PTH 3 (Boundary Commission Trail).

Entering the Municipality of Grassland, the highway travels past the community of Lauder before a junction with PR 345.

PR 254 now makes a sharp left turn to travel just north of the Maple Grove Colony and cross the Souris River.

It now winds its way back and forth as it traverses the Lauder Sand Hills and passes through Grande-Clairière, where it makes a sharp turn to the north at an intersection with PR 541.
