Ma Wan Tung Wan Beach, Public beach in Ma Wan Island, Hong Kong.

Ma Wan Tung Wan Beach is a 140-metre gazetted beach of flat, fine golden sand on the eastern side of Ma Wan Island, near Noah's Ark. It is the only gazetted beach on the island and looks out on the Ting Kau Bridge and the Tsing Ma Bridge, with ships passing in between.

The Hong Kong Government officially recognized this beach in 1991 and opened it to the public in 1993 following the completion of necessary infrastructure work. This timing coincided with broader development projects on Ma Wan Island itself.

The beach's name, Tung Wan, means "east bay" in Chinese, matching its position on the eastern side of Ma Wan island. Since the Park Island estate was completed in 2002, its residents have made the beach a summer destination, and the beach is the only one on the island open to the public.

Three lifeguard posts are staffed on the beach, and toilets sit below an upper-level viewing platform. From Park Island Pier it is about a five-minute walk to the beach; shuttle buses from Tsing Yi Station or Kwai Fong's Metroplaza stop at The Beachside, and buses from Tsuen Wan stop after the Tsing Ma Bridge, a three-minute walk away.

For more than a decade, this beach held the distinction of being the only publicly approved swimming beach in the entire Tsuen Wan district. This made it an exceptionally important location for residents seeking local water recreation.
