Kat Hing Wai is a Punti walled village in the Yuen Long District of Hong Kong. The village is popularly known as Kam Tin, from the name of the local area. Kat Hing Wai is home to about 400 descendants of the Tang Clan, one of the "Five Great Clans" of the territory who settled here from China during the Song Dynasty. The village walls were added in the 17th century. The Tangs are Punti people descended from Southern China and were the first to settle in Hong Kong. Kat Hing Wai's residents speak the Weitou dialect, a Yue dialect.
Three other walled villages, Wing Lung Wai, Tai Hong Wai, and Kam Hing Wai are located nearby and were built around the same time.
