Jarvis Bay Provincial Park, Provincial park in Lacombe County, Canada

Jarvis Bay Provincial Park occupies 0.9 km2 on the eastern shore of Sylvan Lake, 4 km north of the town of Sylvan Lake along Highway 20. Its two campgrounds hold 140 sites in the main loop and 55 tent-only sites in the North Loop, plus four group use areas in the northeast corner. The lakeshore is a steep cliff, so the park has no lake access or beach.

Alberta Parks acquired the land on Sylvan Lake's eastern shore in 1964 and officially established the park in July 1965. This early development made it one of the region's early protected natural areas.

The name Jarvis Bay may honour E.W. Jarvis, a CP Rail surveyor, or W.D. Jarvis, an early North-West Mounted Police inspector; the sources give no firm answer. From 2004 to 2019 the park was among ten Alberta provincial parks under a temporary liquor ban on the Victoria Day long weekend. The lakeshore is a steep cliff, so visitors stay in the campgrounds rather than at a beach.

The lakeshore is a steep cliff, so the park has no lake access or beach; water activities require a short drive to the town of Sylvan Lake. The main campground has 140 sites, while the North Loop offers 55 tent-only sites. Four group-use areas sit in the northeast corner, and 192 sites have electricity in the main season.

The lakeshore below the campground is a steep cliff, so the park has no beach or lake access; water activities require the short drive to the town of Sylvan Lake. The name's origin is uncertain, possibly E.W. Jarvis, a CP Rail surveyor, or W.D. Jarvis, an early NWMP inspector.
