Wong Nai Chung Reservoir Park, Urban park in Southern District, Hong Kong.

Wong Nai Chung Reservoir Park is an urban park centered around an artificial lake with walking paths and open recreational areas set in a natural setting. The site features preserved water control structures including a historic weir, dam works, and valve house from early water management systems.

The reservoir was built in 1889 as Hong Kong's third water storage facility to serve the expanding city. Over time it was transformed into a public park while preserving the original water management structures from that era.

The park displays water infrastructure from Hong Kong's early development, with historic structures still visible today that tell the story of how the city managed water resources. Visitors can observe these old facilities while walking around and appreciate how the community solved practical challenges generations ago.

The park sits on Tai Tam Reservoir Road in Wong Nai Chung Gap, next to Hong Kong Parkview. Green minibuses and local buses serve the gap; the dam top carries a footpath, and the valve house, dam and overflow weir stand close together. Boat rental ran until 14 February 2017 and resumed in April 2022.

The reservoir was a favourite spot for actors Chow Yun-fat and Tony Leung and tycoon Stanley Ho, who came with his young daughter Laurinda. Ducks and mandarin ducks lived on the water until 1997, when the government removed all the birds after an outbreak of avian flu.
