Lido Beach, Public beach in Tsuen Wan District, Hong Kong

Lido Beach is a gazetted bathing beach on Castle Peak Road in Ting Kau, on the western shore of the New Territories, not Kowloon. It is about 200 metres long, sits beside the smaller Casam Beach and the northern abutment of the Ting Kau Bridge, and looks out to the Tsing Ma Bridge.

Lido Beach was gazetted by the Hong Kong government in late 1974 and opened to swimmers in 1975. A two-storey beach building with changing rooms opened on 1 May 1982, built alongside the one at Kadoorie Beach. The beach was closed in 2003 after water quality declined following the commissioning of Stage 1 of the Harbour Area Treatment Scheme, and reopened on 15 June 2011 once disinfection facilities improved conditions.

The name Lido comes from the English word for a bathing beach, rendered in Chinese as 麗都灣. The beach has been called the "Repulse Bay of the New Territories." In summer 2022, the ViuTV drama i.SWIM was filmed here.

The beach has changing rooms, showers, and a kiosk with drinks and snacks for visitors. The best time to swim is from April to October, when lifeguards are on duty and water conditions are safer.

On 29 August 2018 a waterspout formed over the beach and lifted a canoe into the air. The beach also appeared as a filming location for the 2022 ViuTV drama i.SWIM, and in July 2003 two volleyball courts were set up on the sand.
