Provincial Trunk Highway 42 (PTH 42) is a short provincial highway in the southwest region of the Canadian province of Manitoba. It runs from PTH 16 in the town of Shoal Lake to PTH 41 just east of the French-speaking village of St. Lazare.

PTH 42 provides a direct east-west connection through Birtle from PTH 16. As a result, the stretch between Birtle and Shoal Lake is heavily used by trucks as a direct access.^{[citation needed]} The speed limit is 100 km/h (60 mph) east of Birtle and 90 km/h (55 mph) between PTH 83 and St. Lazare.
