Elkhorn is a city in Walworth County, Wisconsin, United States. It is southwest of Milwaukee and northwest of Chicago. The population was 7,305 at the 2000 census. It is the county seat of Walworth County.
In the early 19th century, Colonel Samuel Phoenix spotted a rack of elk antlers in a tree and proclaimed the area as “Elk Horn.”
In 1851, Elkhorn became the location of the Walworth County Fair, which is now hosted annually at the Walworth County Fairgrounds. The Walworth County Fair is the largest in Wisconsin after the Wisconsin State Fair,
Because the city places Christmas decorations around its center, Elkhorn has been called the “Christmas Card Town” since before World War II. This tradition is celebrated every year by an annual oil painting by local artist Jan Castle Reed. These watercolor paintings are turned into Christmas cards.
Elkhorn was a stop on the Racine & Southwestern branch line of the Chicago, Milwaukee, St. Paul and Pacific Railroad, better known as the Milwaukee Road. The Wisconsin & Southern continues to service Elkhorn from a connection at Bardwell to the west.
