Provincial Road 326 (PR 326) is a 22.9-kilometre-long (14.2 mi) highway almost entirely within the Municipality of Bifrost-Riverton in the Interlake Region of Manitoba, Canada.

It connects the town of Arborg with Okno and Fisher Branch.

It heads north along Main Street for a short distance to cross a bridge over the Icelandic River before making a sharp right onto River Road at the southern fringes of downtown.

It parallels the north bank of the Icelandic River as it travels through neighbourhoods before the highway makes a left onto Arborg Avenue, leaving town shortly thereafter and entering the Municipality of Bifrost-Riverton.

The highway heads north through rural farmland for several kilometres, passing through a switchback before having a junction with PR 329 just west of Ledwyn.
