Provincial Road 336 (PR 336) is a 16.4-kilometre-long (10.2 mi) north–south highway in the western part of the Rural Municipality of Morris, Manitoba.

PR 336 begins at an intersection with PTH 23 just east of the community of Kane.

It heads due north along Road 11W, crossing a couple of small creeks via bridges as it travels through rural farmland for several kilometres as a two-lane gravel road.

It traversed portions of the rural municipalities of Rhineland, Morris, and Macdonald.

In 1992, much of PR 336 was decommissioned, like many other highways across the province, leaving only the short section between Kane and Sperling to remain.
