The Bonneville Salt Flats are a 121 km² (47 mi²) salt flat in northwestern Utah. A remnant of the ancient Lake Bonneville, the Salt Flats are now public lands managed by the Bureau of Land Management.

The Salt Flats are perhaps most famous for their use as a raceway for high-speed race cars, which have achieved speeds in excess of 600 miles per hour (1000 kilometers per hour). Several movies have been filmed at the salt flats, including portions of Independence Day (movie).
