Juggling is a physical skill, performed by a juggler, involving the manipulation of objects for recreation, entertainment, art, or sport. The most recognizable form of juggling is toss juggling.

Juggling can be the manipulation of one object or many objects at the same time, using one or many hands. Jugglers often refer to the objects they juggle as props. The most common props are balls, clubs, or rings.

Some jugglers use more dramatic objects such as knives, fire torches or chainsaws. The term juggling can also commonly refer to other prop-based manipulation skills, such as diabolo, devil sticks, poi, cigar boxes, contact juggling,hooping, and hat manipulation.

The earliest record of juggling is suggested in a panel from the 15th Beni Hasan tomb of an unknown Egyptian prince, showing female dancers and acrobats throwing balls. Juggling has been recorded in many early cultures including Egyptian, Chinese, Indian, Greek, Roman, Norse, Aztec (Mexico) and Polynesian civilizations.
