The Golden Triangle can refer to:
- A region located at the junction of Thailand, Laos, and Myanmar. It is called "golden" for the wealth generated by the production and trafficking of heroin.
- A region in China, located south of the Yangtze River in Sunan (southern part of Jiangsu province), between Nanjing to the northwest and Shanghai to the southeast. The "triangle" is formed by the cities of Wuxi, Suzhou, and Changzhou. It is called "golden" because in recent years the region has had one of the fastest-growing economies in China.
