Talat Noi or Talad Noi (Thai: ตลาดน้อย, pronounced [tā.làːt nɔ́ːj]) is a historic neighbourhood in Bangkok. It roughly occupies the area of the sub-district of the same name in Samphanthawong District. On the periphery of Bangkok's Chinatown, Talat Noi has been home to various ethnic Chinese communities since soon after the foundation of Bangkok. Several historic buildings are found in the area, including the Holy Rosary Church, the Talat Noi Branch of Siam Commercial Bank, and the So Heng Tai Mansion.
