Tumbalong Park, Urban park in Darling Harbour, Sydney, Australia

Tumbalong Park is a 5-hectare open lawn in Darling Harbour, bordered by a line of thin trees and low shrubs. A long, low dark-metal structure of rectangular panels on short legs runs across the grass, with a raised rail segment at its left end. Native Australian foliage and fountains forming an urban stream are arranged through the grounds, and a children's playground with a water park of 26 jets, a water slide, jumbo swings, a tangled web and a 10-metre octanet jungle gym sits within the park.

The name Tumbalong comes from Dharug, as spoken by the Eora people, and means "place where seafood is found". The 5-hectare site in Darling Harbour later held Sega World Sydney, which opened in 1997 and closed in November 2000. In 1994 David Kang fired two blank shots at Charles III, then Prince of Wales, during a speech in the park; Charles was unhurt and Kang was arrested.

The park serves as a gathering place for major city celebrations like New Year's Eve and Australia Day, where crowds come together to mark important occasions. This role has made it a focal point for Sydney's public festivities and community events.

Trains reach Town Hall Station, buses run along Market, Park, Druitt, Bathurst and Liverpool Streets, and ferries stop at King Street Wharf or Pyrmont Bay Wharf. Light rail serves the Paddy's Market, Exhibition Centre, Convention and Pyrmont Bay stops. Public toilets, cafes and restaurants sit on the park's fringes, and car parks are nearby.

The children's playground holds a water park with 26 water jets, a water slide, jumbo swings, a tangled web and a 10-metre-high octanet jungle gym. The park also stood in for the skydiving opening scene of 20th Century Fox's Mighty Morphin Power Rangers: The Movie.
