County Fair Guide

The Oldest Fairs in Iowa

Iowa's oldest fair is the Iowa State Fair itself, running in Des Moines since 1854 — eight years after Iowa became a state in 1846, and predating every county fair in the state. The Clay County Fair in Spencer (1918) and Scott Mississippi Valley Fair in Davenport (1920) both trace back to the years around World War I, and both remain among the largest county fairs in the country today. Here are Iowa's fairs with the longest documented histories.
