Thunderbird, Steel roller coaster in Santa Claus, Indiana, US.

Thunderbird is a steel roller coaster at Holiday World that launches riders to about 60 miles per hour (97 kilometers per hour) in 3.5 seconds before sending them through multiple inversions. The track features a 140-foot (43-meter) Immelmann loop and other elements that create unique sensations throughout the ride.

Holiday World announced Thunderbird on July 24, 2014, as its first major steel coaster and the first launched Wing Coaster in the United States. Track and supports arrived the following week, the first two inversions were topped off by October, and construction finished in early December 2014. The ride opened on April 25, 2015; Prairie Farms Dairy sold a vanilla, caramel and roasted pecan ice cream named after it.

PGAV Destinations built the ride's visual theme around the legendary bird's flight over the farms and forests of southern Indiana. The launch is preceded by a pre-show of fog, lighting and thunder sound effects that simulates a thunderstorm. Prairie Farms Dairy sold a "Thunderbird" ice cream of vanilla with caramel and roasted pecans to mark the 2015 opening.

Riders must be between roughly 52 and 78 inches (132–198 centimeters) tall and should store loose items in designated areas before boarding. Different seat positions offer varied experiences, so trying multiple spots on different visits can enhance your overall enjoyment.

The launch machinery sits in a separate building called Will Power, named after former park president Will Koch, who died in 2010. Each launch draws 2.5 megawatts, stored in generators with two 24,000-pound flywheel assemblies. Thunderbird was also the first Bolliger & Mabillard coaster to use an LSM launch.
