Bonnie is a village located in the southern part of Jefferson County, Illinois.

The first settlement in this area was Spring Garden, about four miles southeast of Bonnie.

Spring Garden grew rapidly, becoming the second largest settlement in the County, even having a high school by 1888.

Spring Garden began a long decline as the business and population shifted to the rail depots at Bonnie and Ina.

George Washington Hayes (1842–1927) donated some of the land originally making up Bonnie.

This campground has been the scene of large religious outdoor gatherings since late in the 19th century.

Approximately 21.5% of all households were made up of individuals, and 11.9% had someone living alone who was 65 years of age or older.
