Hayward Lake Trail is a scenic lakeside route near Mission in the north-central Fraser Valley of British Columbia. The trail runs along the Hayward Lake Reservoir, which forms part of BC Hydro's Stave River hydroelectric project, bounded by the Ruskin Dam.

The full out-and-back route covers approximately 12 kilometres and takes around 3. 5 hours to complete. The trail combines forested shoreline paths, dam crossings, and waterfall viewpoints, including a spur to Steelhead Falls.

Two out-and-back trails surround the lake, with the north and south ends crossing BC Hydro-owned land for roughly 2 kilometres each. Visitors are asked to stay on marked trails to protect the natural environment.

The area sits within the traditional territory of the Kwantlen, Musqueam, and Stó:lō First Nations and is especially popular on weekends and holidays.
