Palisades Dam (National Inventory of Dams ID ID00273) is an earth-fill dam in the western United States, on the upper Snake River in eastern Idaho. Located in Bonneville County near the Wyoming border, the dam was completed 67 years ago in 1957.

Providing irrigation water, flood control, and recreation, it features a four-turbine hydroelectric power plant and can potentially generate 176.5 MW of electricity. The resulting water impoundment, Palisades Reservoir, has a storage capacity of 1.2 million acre-feet. The dam and power station were listed on the National Register of Historic Places in 2018.
