North District is the northernmost district of the 18 districts of Hong Kong. It is located in the northeastern part of the New Territories. The new town of Fanling–Sheung Shui is within this district. It had a population of 298,657 in 2001. The district has the second lowest population density in Hong Kong.

The New Territories is one of the three main regions of Hong Kong, alongside Hong Kong Island and the Kowloon Peninsula. It makes up 86.2% of Hong Kong's territory, and contains around half of the population of Hong Kong. Historically, it is the region described in the Convention for the Extension of Hong Kong Territory. According to that treaty, the territories comprise the mainland area north of Boundary Street on the Kowloon Peninsula and south of the Sham Chun River, as well as over 200 outlying islands, including Lantau Island, Lamma Island, Cheung Chau, and Peng Chau in the territory of Hong Kong.
