Yellowstone Lake State Park is a state park in Lafayette County, Wisconsin, United States. The park surrounds the 455-acre (184 ha) Yellowstone Lake, a reservoir along the Yellowstone River. It is included in the 4,047-acre (1,638 ha) Yellowstone Wildlife Area.

The park has 128 campsites and 5 group sites. There is a swimming area with sand beach, picnic areas, playgrounds, and a boat launch. Boating and fisghing, particularly for bluegill, largemouth bass, walleye and channel catfish is popular, with some northern pike and muskellunge. The adjacent 4,000-acre wildlife area offers extensive horse trails and a shooting range.

The man-made lake is sustained by the Yellowstone River, a tributary of the Pecatonica River which enters on the northwest side, and the man-made dike built on the southeast side. The dam at the southern end of the dike is crossed by a narrow, steel catwalk, from which fishing is not allowed.
