The Windy City ThunderBolts are an independent professional baseball team based in Hoffman Estates, Illinois, a western suburb of Chicago.

History
- Origins (2004–2009): The franchise originated as the Schaumburg Flyers, a team that entered the independent Northern League in 1999. After the Flyers suspended operations in 2009 due to financial difficulties, the franchise rights were transferred.
- Re‑establishment (2010): In 2010, the team was re‑branded as the Windy City ThunderBolts and joined the Frontier League. The name references Chicago’s nickname “the Windy City” and the “Thunderbolts” moniker was selected through a fan‑participation naming contest.
- Relocation: While retaining the original franchise’s historical continuity, the ThunderBolts began playing at Riverton Stadium in Hoffman Estates, moving from the previous Schaumburg venue.
