Ngau Kwu Long (Chinese: 牛牯塱; lit. 'cattle pasture valley') is a village on Lantau Island, Hong Kong, located near Tai Ho Wan, a bay on the northern shore of Lantau Island, and northeast of Tung Chung.

Ngau Kwu Long is a recognized village under the New Territories Small House Policy.

Ngau Kwu Long is a single-surname village, occupied by members of the Lam (林) family. The Lams originated from Putian in Fujian province. They moved to Chayuan (茶園) of Dongguan in Guangdong province, and a branch of the family moved to Ngau Kwu Long during the reign of Qianlong Emperor (1736-1796).

Ngau Kwu Long was historically part of the San Heung (三鄉) community, consisting of the villages of Pak Mong, Ngau Kwu Long and Tai Ho.

The village is located along the Hong Kong Olympic Trail, a 5.6 km long "Olympic Route" connecting Pak Mong to Mui Wo that was opened in celebration of Hong Kong's hosting of the equestrian events in the July 2008 Olympics.
