Boomsday is a fireworks event in Knoxville, Tennessee held on Labor Day weekend every year. Taking place on the waterfront in downtown Knoxville, Boomsday is the largest fireworks show in the Southeast United States and has been visited by dignitaries from the Middle East and Europe. As one of the biggest events in Tennessee, it is a top attraction in the region and has even been filmed by National Geographic for a television special. The term Boomsday comes from the booming sound of the hundreds of fireworks that create the highlight of the event.
Held on Volunteer Landing and Neyland Drive in Knoxville, the Boomsday celebration attracts spectators for around the United States. Nearly 325,000 people attend the event usually on Sunday at the beginning of September, and the fireworks can be viewed from any of a number of locations around the waterfront.
