The first Portage County Fair Association was organized in 1869. The first fair was held that same year. The Portage County Fair was held continuously from 1869 to 1917 at Amherst, Wisconsin. In 1917 the officers of the association voted not to hold the 50th fair — 1918 — that year but to have a big homecoming affair because many of the boys were in World War I service. The fair will be held July 18-21 at the fairgrounds at 4504 Fairground Road, Amherst, Wisconsin. Visit for more information. Visit for more information on all Wisconsin fairs.
