Jalan Besar Stadium, officially the Jalan Besar ActiveSG Stadium, is a football stadium located in Kallang, Singapore. The stadium is part of the Jalan Besar Sports and Recreation Centre, a community sports facility.

It is the home ground of the Singapore Premier League club Young Lions. The stadium is also used as an alternative home ground to the National Stadium by the Singapore national football team. The Football Association of Singapore (FAS) is also headquartered within the stadium.

Jalan Besar Stadium is located along Tyrwhitt Road, within the close proximity of the major road Jalan Besar, hence its name.

The original stadium was opened on Boxing Day 1929 by president of the Municipal Commission of Singapore, R. J. Farrer, with the nearby Farrer Park named after him. It is considered to be the birthplace of Singapore football. Malaya Cup matches were played at the stadium from 1932 to 1966, and Malaysia Cup matches from 1967 to 1973.

During the Japanese Occupation, the stadium was one of the Sook Ching mass screening sites orchestrated by Japanese officials. During the war, the stadium remained opened and was also used as a language centre to teach the Japanese language to locals.

On 12 November 1956, the United States men's national soccer team (USMNT) for the 1956 Summer Olympics played an exhibition game against the Singapore team at the Jalan Besar Stadium.

On 30 May 1964, a mass rally led by Singaporean statesman Lee Kuan Yew was held at the stadium to mourn and honour the death of Indian statesman Jawaharlal Nehru, whom Lee considered "a staunch friend" during the decolonisation era after World War II. Nehru had previously spoke at the stadium when he visited the country in June 1950, calling for "peace and conciliation" in the region while decolonisation was underway.

The stadium was also host to many major events in Singapore's history, such as being the venue for the first Singapore Youth Festival in 1955, the first Singapore Armed Forces Day in 1969, and the 1984 National Day Parade.
