Trempealeau County is a county located in the U.S. state of Wisconsin. As of 2000, the population was 27,010. Its county seat is Whitehall6.


Patches of woodland are all that remain of the brush and light forest that once covered the county. In ancient times, the woodlands contained a great deal of timber, but Native Americans burned them periodically to encourage the growth of berries. They did little cultivation and had been almost completely removed from the area by 1837 (Gamroth, 1976, p. 5, 87).

French fur traders were the first Europeans to enter this land. At the mouth of the Trempealeau River, which flows from northeast to southwest across the county on its way to the Mississippi River, they found a bluff surrounded by water and called it "La Montagne qui trempe à l’eau," which means "mountain with its foot in the water." The name was later shortened (Elkins, 1985, p.1).


According to the U.S. Census Bureau, the county has a total area of 1,922 km² (742 sq mi). 1,901 km² (734 sq mi) of it is land and 20 km² (8 sq mi) of it (1.06%) is water. It is part of the Driftless Zone.
