The Macleay Museum at The University of Sydney, was a natural history museum located on the University's Camperdown campus, in Sydney, New South Wales, Australia.

[1] The Macleay Museum was added to the City of Sydney local government heritage list on 14 December 2012.

[2][3] The Edgeworth David building in which the museum was housed was built off Science Lane within the Camperdown campus in 1887.

[4] The strengths of the collection, now part of the Sydney University Museums, were in entomology, ethnography, scientific instruments, and historic photographs.

Many of the biological specimens in the collection represented rare or extinct species, while some of the specimens have historic and cultural value[5] as they were collected by explorers like Charles Darwin and Nicholas Miklouho-Maclay.
