Association football in Vietnam is run by the Vietnam Football Federation. The federation administers the Vietnam national football teams, as well as the national football leagues.
Football (Vietnamese: Bóng đá) is unarguably the main and most popular sport in Vietnam. Its annual V-League competition has taken place since 1980 till now (except in 1988 and 1999).
When Vietnam was split into North Vietnam and South Vietnam, two national teams existed. The North Vietnamese team was not very active, playing almost exclusively other Communist countries between 1956 and 1966 whilst the South Vietnamese team took part in the first two AFC Asian Cup finals, finishing fourth both times.
Football came into Vietnam with the French in 1896. It was first introduced in Cochinchina (Nam Kỳ), and then spread to other parts of the colony - the central and northern parts.
The first people who played football in Saigon were French civil servants, merchants and soldiers; some Vietnamese then picked it up. A club called Cercle Sportif Saigonnais (Saigon Sports Circle) was founded and later the oval-shaped ball was replaced by a round-shaped one and the games were played at the city park, called Jardin de la Ville (today Tao Đàn Park).
In 1905, a British warship named after King Alfred visited Saigon and its football team had a friendly match against a local team composed of Vietnamese and French players. This was considered as the first international football match in Vietnam.
E. Breton, a member of France's L'Union des Sociétés Français des Sports Athlétiques brought football rules into Vietnam in 1906, and as a chairman of Cercle Sportif Saigonnais, he reorganized the club similar to football clubs in France. Some other clubs started to appear, such as Infanterie, Saigon Sport, Athletic Club, Stade Militaire, Tabert Club. Local cups were soon held afterwards. As a well-trained team, Cercle Sportif Saigonnais won for many times, 1907, 1909, 1910, 1911, 1912, 1916.
Some Vietnamese learned the game's regulations and established their own teams. The first two Vietnamese teams founded in 1907 were Gia Định Sport run by Ba Vẻ and Phú Khai and Ngôi Sao Xanh (Blue Star) run by Nguyễn Đình Trị. These two teams then came together to form "Ngôi sao Gia Định" (Gia Định Star). Prior to 1920, it had defeated all other teams, including Cercle Sportif Saigonnais (in 1917), and became the champion.
