The Livermore Rodeo is a rodeo held annually in Livermore, California on the second full weekend of June at the rodeo grounds at Robertson Park. It is the oldest event in Livermore and part of the famous California 6-Pack Rodeo Circuit. Famous rodeo participants frequent the event and it is often used as a backdrop or exteriors site in films. It is always preceded by the Rodeo parade  through the Livermore Downtown area on Saturday morning of the rodeo weekend, and has had concerts by Country and Western musicians, including Mark Chesnutt in 2005. The Rodeo Association also hosts a Family Night during Rodeo week and a Volunteer Appreciation party after the rodeo is over. It is advertised as the "world's fastest rodeo".
During World War I, in 1918, the Red Cross was in dire needs of funds, so California cities and towns were assessed $1200 each as a way of generating the needed money. John McGlinchey, who was president of the Livermore Stockman's Protective Association at the time, conceived the idea of holding a fund-raiser in the form of a rodeo to raise the money. A committee was appointed by McGlinchey to organize the rodeo, which was held the first time on a portion of a local ranch near the intersection of what is now Interstate 580 and Portola Avenue. The opening event was filmed by Universal Studios for a newsreel.
