Castle Peak Beach (Chinese: 青山灣泳灘) is a gazetted beach in Tuen Mun, Hong Kong, beside Sam Shing Estate. It looks onto Castle Peak Bay and the Tuen Mun typhoon shelter, although it is separated from the typhoon shelter by a breakwater.

The beach comprises 2.97 hectares and has a swimming zone of 0.8 hectares protected by a shark net. It was closed from 1981 to 2005 due to water pollution. In the summer months it is staffed by lifeguards of the Leisure and Cultural Services Department (LCSD).

Historically, the beach was known as Yung Lung Beach and was a very attractive place for swimming. It was closed for swimming in 1981 due to poor water quality. In September 1983 the beach was badly damaged by a typhoon that caused the loss of sand and trees.

In November 1994 the Tuen Mun District Board made a request to open the beach for swimming and leisure. In response, the Regional Council built several facilities at a cost of HK$97 million including a barbecue area, a sitting-out area, a children's play area, and a two-storey beach building with toilets, changing rooms and showers. In November 1999 the beach was handed over to the Regional Services Department. However, the beach was still not opened for swimming owing to a layer of mud and refuse on the seabed. In May 2000 the beach facilities were opened to public use, though the water remained off-limits.

From December 2001 to August 2002 the then-Civil Engineering Department (CED) undertook dredging and sand-filling works at a cost of $1.9 million. The layer of soft mud was removed to improve the water quality. However, in October 2002 the CED reported that the beach was still not suitable for swimming, and the LCSD decided the beach would continue to be closed.

Other attempts to improve water quality were made over the years. In 1993 a new trunk sewer was built along Castle Peak Road, from So Kwun Wat to Sam Shing Estate, directing sewage from the hinterland to the Pillar Point Sewage Treatment Works. Additionally, the North Western Water Control Zone was declared under the Water Pollution Control Ordinance, controlling pollution. In 1999 a longer submarine outfall came into operation at the Pillar Point Sewage Treatment Works, directing effluent farther away from the beaches. In the early 2000s two dry weather flow interceptors were installed along the Tuen Mun River, which discharges into Castle Peak Bay, to intercept village sewage and other pollutants before it reaches the river.
