Cheerleading is an activity in which the participants (called cheerleaders) cheer for their team as a form of encouragement. It can range from chanting slogans to intense physical activity. It can be performed to motivate sports teams, to entertain the audience, or for competition. Cheerleading routines typically range anywhere from one to three minutes, and contain components of tumbling, dance, jumps, cheers, and stunting. Cheerleading originated in the United States, where it has become a tradition. It is less prevalent in the rest of the world, except via its association with American sports or organized cheerleading contests.

Modern cheerleading is very closely associated with American football and basketball. Sports such as association football (soccer), ice hockey, volleyball, baseball, and wrestling will sometimes sponsor cheerleading squads. The ICC Twenty20 Cricket World Cup in South Africa in 2007 was the first international cricket event to have cheerleaders. The Florida Marlins were the first Major League Baseball team to have a cheerleading team.

Cheerleading originated as an all-male activity in the United States, and is popular predominantly in America, with an estimated 3.85 million participants as of 2017.^[1] The global presentation of cheerleading was led by the 1997 broadcast of ESPN's International cheerleading competition, and the worldwide release of the 2000 film Bring It On. The International Cheer Union (ICU) now claims 116 member nations with an estimated 7.5 million participants worldwide.^[2]

Around the end of the 2000s the sport had gained traction outside of the United States in countries like Australia, Canada, Mexico, China, Colombia, Finland, France, Germany, Japan, the Netherlands, New Zealand, and the United Kingdom.^[3] However, the sport does not have the international popularity of other American sports, such as baseball or basketball, despite efforts being made to popularize the sport at an international level. In 2016, the IOC (International Olympic Committee) recognized the ICU (International Cheer Union) as part of the sports federations; in practice this means that the modality is considered a sport by the IOC, and in the future, depending on negotiations and international popularization, it could become part of the Olympic Games.

Scientific studies of cheerleading show that it carries the highest rate of catastrophic injuries to female athletes in sports, with most injuries associated with stunting, also known as pyramids. One 2011 study of American female athletes showed that cheerleading resulted in 65% of all catastrophic injuries in female sports.^[4]
