Stanley Park is a 404.9 hectare (1,000 acre) urban park bordering downtown Vancouver, British Columbia, Canada. It was opened in 1888 by Lord Stanley of Preston, the Governor-General of Canada.

It is the largest city-operated park in Canada and the third largest in North America. It is more than 10% larger than New York City's Central Park and almost half the size of London's Richmond Park. The park attracts an estimated eight million visitors every year, including locals and tourists, who come for its recreational facilities and its natural attributes.

An 8.8 kilometre (5.5 mile) seawall path circles the park, which is used by 2.5 million pedestrians, cyclists, and inline skaters every year. Much of the park remains forested with an estimated half million trees that can be as tall as 76 metres (250 ft) and hundreds of years old. There are approximately 200 km (125 miles) of trails and roads in the park, which are patrolled by the Vancouver Police Department's equine mounted squad.

The Project for Public Spaces has ranked Stanley Park as the sixteenth best park in the world and sixth best in North America.
