The Botanic Gardens and Parks Authority is a Western Australian State Government authority. It was formed in 1999, following the proclamation of the Botanic Gardens and Parks Authority Act 1998 and Regulations 1999.

The two major incentives for this new Act were to update legislation that had been operating for the management of Kings Park and Botanic Garden by the Kings Park Board since 1895 and to provide legislation for the Authority to manage other designated lands, such as Bold Park (which was declared an A class reserve in August 1998). Kings Park and Bold Park are two of Perth's largest reserves, incorporating the State's Botanic Garden and important urban bushland areas.

The Authority's vision is to create and provide world-recognised botanic gardens and parks and to inspire the conservation of biological diversity. Many staff and volunteers work enthusiastically to make both parks the inspiring places they are today.

The Authority conducts business from head office in Kings Park on Fraser Avenue, West Perth and from the Western Australian Ecology Centre located in Bold Park, Floreat.
