The Allan Green Conservatory was a pyramid shaped botanical display facility on the Esplanade Reserve in Perth, Western Australia. It was built in 1979 as part of the state's 150th anniversary celebrations and was designed to provide a public display of exotic tropical plants and rare palms not normally seen in Perth. It included internal elevated pathways. It was named after William Allan McInnes Green, town clerk and chief executive officer of the City of Perth for many years.
