Edinburgh Zoo (Scottish Gaelic: Sù Dhùn Èideann), formerly the Scottish National Zoological Park, is an 82-acre (33 ha) non-profit zoological park in the Corstorphine area of Edinburgh, Scotland.
The zoo is positioned on the south-facing slopes of Corstorphine Hill, giving extensive views of the city. Established in 1913, and owned by the Royal Zoological Society of Scotland, it receives over 600,000 visitors a year, which makes it one of Scotland's most popular paid-for tourist attractions. As well as catering for tourists and locals, the zoo is involved in many scientific pursuits, such as captive breeding of endangered animals, researching into animal behaviour, and active participation in various conservation programmes around the world.
Edinburgh Zoo was the first zoo in the world to house and breed penguins. It is the only zoo in Britain to house Queensland koalas and, until December 2023, giant pandas. The zoo is a member of the British and Irish Association of Zoos and Aquariums (BIAZA), the European Association of Zoos and Aquaria (EAZA), the World Association of Zoos and Aquariums (WAZA), and the Association of Scottish Visitor Attractions. It has also been granted four stars by the Scottish Tourism Board. The zoo gardens boast one of the most diverse tree collections in the Lothians.
