Ang Soon Tong (Chinese: 洪顺堂; Pe̍h-ōe-jī: âng sūn tông) is a secret society based in Singapore and Malaysia. According to a former police officer, the society was active as early as the 1950s, mainly in the Sembawang area. In 1998, a 19-year-old youth was arrested for setting up a website dedicated to the society.
As recently as 2020, Ang Soon Tong is still active, with one of its members sentenced to reformative probation that year for clashing with members of another secret society.
The gang gain profits through illegal activities such as smuggling and trading of gun and drugs, illegal moneylending and illegal gambling.
