Cheyenne Frontier Days is an outdoor rodeo and western celebration in the United States, held annually since 1897 in Cheyenne, Wyoming. It bills itself as the "World's Largest Outdoor Rodeo and Western Celebration." The event, claimed to be one of the largest of its kind in the world, draws nearly 200,000 annually. Lodging fills up quickly during the peak tourist season throughout southern and eastern Wyoming, into northern Colorado and western Nebraska. The celebration is held during the ten days centered about the last full week of July. In 2008, Cheyenne Frontier Days was inducted into the ProRodeo Hall of Fame.

Frontier Days delivers three types of competition: roughstock events, timed events, and racing on the track. Roughstock events include bull riding, bareback bronc riding, saddle bronc riding, and rookie saddle bronc riding. Timed events include steer wrestling, team roping, tie-down roping, and women's breakaway roping & barrel racing. Tie-down roping includes calf roping, steer roping, and senior steer roping. Some of the timed events are shown during slack. After all of the events are concluded, there is an all-around champion winner.

Cheyenne Frontier Days in 2014 received the Professional Rodeo Cowboys Association (PRCA) Large Outdoor Rodeo of the Year award for the 16th total and 11th consecutive time. Frontier Days runs nine days with more sections of bull riding, saddle and bareback bronc riding than any other rodeo.
