Provincial Road 240 (PR 240) is a 122.8-kilometre-long (76.3 mi) north–south highway in the Pembina Valley and Central Plains regions of Manitoba, connecting the hamlets of Darlingford, Miami, Roseisle, and St. Claude with the city of Portage la Prairie, as well as providing the only road access to the hamlet of Delta Beach on Lake Manitoba.

Now paved, the highway heads east to pass by Alexander Ridge Park before PR 240 splits off as a gravel road again just prior to reaching the hamlet of Miami.

It now enters the hamlet of St. Claude, mostly travelling along the community's western edge to cross a railroad and have an intersection with PTH 2 (Red Coat Trail).

The highway passes a hospital and then runs concurrently with PTH 1A (Saskatchewan Avenue E) and the highway heads west as a four-lane divided boulevard to enter the center of downtown, where PR 240 splits off and heads north as a two-lane along Tupper Street N. PR 240 crosses a railroad to travel past several neighbourhoods before leaving Portage la Prairie and passing through rural farmland for the next several kilometres, where it travels past the First Homestead in Western Canada National Historic Site.

[1] It has a short concurrency with PR 227 in the hamlet of Oakland before continuing north through first farmland, then some marshy areas, before entering Delta Beach and coming to an end at an intersection with Hackberry Avenue W, just metres from the coastline of southern Lake Manitoba.
