Rolley Lake Provincial Park, Provincial park in Fraser Valley Regional District, Canada

Rolley Lake Provincial Park is a nature reserve with a circular lake surrounded by second-growth coniferous forest and multiple walking trails. The terrain features forested slopes leading down to the water, with pathways suitable for different experience levels.

The territory was originally home to the Sto:lo people before James and Fanny Rolley established their homestead in 1888. Logging operations later shaped the landscape until the area was eventually protected as a provincial park.

The park lies in the traditional territory of the Sto:lo people, who inhabited the area before James and Fanny Rolley homesteaded it in 1888. The name Rolley Lake comes from this family, and later logging operations also left their mark on the land.

The park has a day-use area and a camping site; the Rolley Falls hike begins at the campsite and runs 2.5 km out and back to nearby waterfalls. The Rolley Lake trail is an easy 3 km loop around the lake. The park lies 417 m above sea level, 14.8 km east of Maple Ridge, and receives about 2,359 mm of precipitation a year, so rain gear is useful in any season.

Rolley Lake sits 417 metres above sea level, and Maple Ridge lies 14.8 km to the west. The surrounding mixed forest is dense: about 139 people live per square kilometre in the area around the park. Recorded extremes at the lake run from −26.7 °C on 31 January 1929 to 40.0 °C on 25 June 1925.
