Lake Redstone is in La Valle in northern Sauk County of Wisconsin, United States.

Lake Redstone is a reservoir. Construction of the lake was started in 1964. The lake's surface area is approximately 650 acres (2.6 km²), with over 17 miles (27 km) of shoreline and 4½ miles long. Lake Redstone has no mandatory owners association, but owners are encouraged to join the Lake Redstone Property Owners Association. Lake Redstone has a 19,200-acre (78 km²) watershed to the north from Juneau County that fills the lake. The dam is located at the south end and has a top draw spillway. All excess water creates a cascading waterfall and eventually flows into the Baraboo River. It is located in Sauk County, approximately seven miles from Reedsburg, and only three miles from LaValle.
