Angophora Reserve, Nature reserve in Northern Beaches, Sydney, Australia.

Angophora Reserve is a nature reserve in Northern Sydney covering roughly 18 hectares of diverse habitats mixed together. The space features woodlands, open forests with native trees, palm groves, fern swamps, and sedge-filled wetlands across its area.

The Wildlife Preservation Society purchased this land in 1937 to protect a giant Angophora Red Gum tree, which was officially opened to the public in 1938. That single tree became the reason this entire area remained protected as a nature reserve.

The reserve contains an Aboriginal shelter site of archaeological and cultural importance, described in the sources as one of the most important of its kind in the Sydney region. It is one of the features that led to the reserve's listing on the Register of the National Estate.

Angophora Reserve borders Avalon Beach, Clareville and Taylors Point, and tracks can be joined from streets on those sides, including Wandeen Road, Hilltop Road, Chisholm Avenue, Bilwarra Avenue, The Circle and Palmgrove Road. Paths cross several terrain types, so wear sturdy shoes. The reserve was created as a bushland sanctuary, so stay on the formed tracks.

The reserve began as a sanctuary for a single giant Angophora Red Gum estimated at 1,000 years old; the tree still stands but is now dead. Sir Philip Whistler Street opened the reserve beneath it on 19 March 1938.
