Gillespie is a city in Macoupin County, Illinois, United States, and part of the Metro East region of the St. Louis metropolitan area. The population was 3,168 at the 2020 census.^[3]

The first group of settlers arrived to the area of Gillespie in the late 1820s from Kentucky, Ohio, and Indiana.^{[citation needed]} The township thrived in the 1830s, increasing in population and businesses. In 1835 the first schoolhouse was built. Gillespie was incorporated as a town in the spring of 1853.^{[citation needed]} By 1904, the population rose to 3,100 and there were a number of businesses, churches, and schools. On January 29, 1905, a fire swept through the business district and destroyed most businesses and some homes.^[4]

For years, Gillespie's main source of employment were the multiple coal mines scattered throughout the township operated by the Chicago & Northwestern Railway. It is said that Gillespie boasted three of the largest coal mines in the world.^[4]

Gillespie is named for Judge Joseph Gillespie, who was active in Illinois state politics.^[5][6]
