Bonneville County was established in 1911, named after Benjamin Bonneville (1796–1878), a French-born officer in the U.S. Army, fur trapper, and explorer in the American West.
The name was taken from the Bonneville Salt Flats in Utah, the site of much early auto racing and most of the world's land speed record runs, which was named in turn after U.S. Army officer Benjamin Bonneville.
Walker Pass was charted as route through the Sierra in 1834 by Joseph R. Walker and Garland Guthary, members of the Bonneville Expedition who learned of it from Native Americans.
