Kwai Chung Park, Public park in Kwai Tsing District, Hong Kong.

Kwai Chung Park is a partly built park on the former Gin Drinkers Bay landfill in southern Kwai Chung, New Territories. Its first phase, opened on 17 December 2025, has landscaped gardens, a children's playground with a 5-metre slide, a fitness area, jogging and walking trails, a pet garden and a performance stage. A footbridge links it to Kwai Shing Estate.

The site was a bay at Gin Drinker's Bay that was reclaimed and used as a landfill until it closed in February 1979. In 1981 the colonial government planned a large town park to rival Victoria Park and Kowloon Park, and works were tendered in 1982. Landfill gas from decomposing waste blocked the opening planned for 1992, and the Airport Railway later cut a valley through the central lawn.

The park's name comes from Kwai Chung, and its site was the Gin Drinkers Bay landfill, closed in February 1979. The 3.9-hectare Hong Kong Jockey Club International BMX Park opened there on 31 October 2009 as the venue for that year's East Asian Games BMX events, with a 350-metre international-standard track and a 60-metre training track; users pay a fee.

The first phase, reopened on 17 December 2025, is reached by a new ramp-and-lift link from Kwai Yu Street; a footbridge also connects the park to Kwai Shing Estate. The cricket ground in phase two opens to the public for walking and morning exercise on weekday mornings, roughly 7 to 9 am. The BMX track charges a fee for use.

The park's first phase opened on 17 December 2025, after the site spent decades closed because decomposing landfill waste released marsh gas. The Environmental Protection Agency recorded maximum gas readings of 0 to 30 ppm from 2001 onward, well below the 500 ppm US EPA guideline. The 5-metre slide in the children's playground is among the new facilities.
