Kam Tin or Kam Tin Heung , is an area in the New Territories, Hong Kong. It is north of Tai Mo Shan and east of Yuen Long. It was formerly known as Sham Tin (). Administratively, it is part of Yuen Long District. Many of Kam Tin's residents are from the Tang Clan, who are of the Punti culture, not Hakka as is often misattributed. Kam Tin is the origin of the biggest indigenous Tang Clan () in Hong Kong. The ancestor of indigenous Tang, Tang Hon Fat () settled his family from Jiangxi to Sham Tin in 973. During the reign of Wanli Emperor (15721620) of Ming Dynasty, Sham Tin was renamed Kam Tin.
