ByronFest, one of the finest family festivals in Northern Illinois, is held annually during the second full weekend in July. The festival is located in Byron's downtown area. Additional events are held in other venues throughout the city, including athletic events at the Byron Park District and Jarrett Prairie Center, a classic car show at the United Church of Byron and quilt show at the Byron Museum of History.
ByronFest is a venture of the Byron Chamber of Commerce designed to encourage and promote tourism in the Byron area and to showcase the Byron community to the many visitors who travel to Byron for the three-day event. In addition, the festival provides an opportunity for many not-for-profit organizations to raise funds for various projects. During the past twenty-five years, ByronFest has returned over a million dollars to local charitable groups. These organizations have in turn used the funds for community improvements and programs throughout the area.
Some local organizations that have taken advantage of this opportunity include Byron Lions Club, Byron Kiwanis Club, Byron Key Club, Byron Firemen's Association, Boy Scouts, Byron High School Cross Country, Byron High School Volleyball, and many others.
