Beach volleyball, or sand volleyball, is an Olympic team sport played on sand. Like other variations of volleyball, two teams, separated by a high net, try to score points against the other by grounding a ball on the other team's court. Competitive beach volleyball teams usually consist of two players, though recreational variations can contain up to six players.

Originating in Southern California, beach volleyball now enjoys worldwide popularity, even in countries without traditional beaches, like Switzerland.

Though popularized in Southern California, the first recorded beach volleyball games took place on the beaches of Waikiki in Honolulu, Hawai'i at the Outrigger Canoe Club.[1] Originally designed to give bored surfers something to do when the surf was down, the game quickly developed into more organized six-man matches. The most famous early player was legendary waterman, Duke Kahanamoku.

In 1920, construction of new jetties in Santa Monica, California created a large sandy area for public enjoyment, planting the seed for beach volleyball development in that region. The first permanent nets began to appear, and recreational games were soon being played on public parts of the beach, as well as in private beach clubs. 11 such beach clubs appeared in the Santa Monica area, beginning in late 1922. The first inter-club competitions were staged in 1924, marking the first beach volleyball tournaments to be played in California.

Most of these early beach volleyball matches were played with teams of at least six players per side, much like indoor volleyball. The concept of the modern two-man beach volleyball game, however, is credited to Paul "Pablo" Johnson, an indoor player.[2] In the summer of 1930, while waiting for players to show up for a six-man game, Johnson decided to try playing with only the four people present. The game was forever changed.
