Griggsville is a rural town in Pike County, Illinois, United States.

The community is in northeast Pike County approximately four miles west of the Illinois River.

Griggsville hosts the Apple Festival on the third weekend of each September, along with the Western Illinois Fair, traditionally held during the third week of June.

Amid growing concern over the use of pesticides to control mosquitoes, the town came up with an alternate abatement method.

Wade, a Griggsville resident and owner of a local antenna manufacturing factory realized that Griggsville was right in the migration path of the purple martin, the largest bird in the swallow family, supposedly able to eat 2,000 mosquitoes in a single day.

Wade quickly realized that to get the purple martins to stay, he simply needed to give them a reason to stay, so he converted his antenna factory into a bird house building factory.
