Dillberry Lake Provincial Park, Provincial park in Alberta, Canada

Dillberry Lake Provincial Park is a protected area featuring a freshwater lake surrounded by rolling hills and sand dunes across roughly 12 square kilometers (4.6 square miles). The park includes camping grounds, two beaches, boat access points, and walking trails that let visitors move through and explore the natural landscape.

The park was established in 1957 as an effort to protect natural spaces in the region. Its creation reflected a growing commitment to preserving landscapes for future generations.

The park lies within the Killarney, Dillberry and Leane Lakes Important Bird Area, a designation shared with the neighbouring Killarney-Reflex Lakes heritage rangeland. Birders look for ducks, geese, swans and herons alongside hermit thrushes, lark sparrows, marsh wrens, yellow-headed blackbirds, western meadowlarks and Sprague's pipits. The origin of the park's name is unknown.

The park lies along Highway 17, 43 km north of Provost and 17 km south of Chauvin, at an elevation of 620 m. Two beaches are maintained, a day-use beach and a campers beach, and the Loon Loop and Ranger Loop trails are kept for front-country hiking. Rainbow trout fishing continues in winter as ice fishing.
