Provincial Road 323 (PR 323) is a 26.5-kilometre-long (16.5 mi) east-west highway in both the Interlake and Winnipeg Capital regions of Manitoba, Canada.

It heads due east as a two-lane gravel road through rural farmland for several kilometres, where it becomes concurrent with PR 322 just prior to entering the town of Argyle and the Rural Municipality of Rockwood.

Being paved as it travels through the centre of town, PR 322 splits off and heads south shortly thereafter, with PR 323 becoming unpaved once more as it leaves Argyle and heads east through rural farmland.

The highway crosses PR 236 just north of Stonewall before coming to an end at an intersection with PTH 7.

[1][2] Prior to 1992, PR 323 continued on further west past PTH 6 for 8 kilometres (5.0 mi) to come to an end at a junction with PR 248 north of Meadow Lea.
