Fish Creek Provincial Park, Provincial park in south Calgary, Canada

Fish Creek Provincial Park protects the valley of Fish Creek in south Calgary, bordered on three sides by the city and on the west by the Tsuu T'ina Nation. The park covers 13.48 km2 and stretches 19 km from east to west. Fish Creek flows through the valley to join the Bow River, and the stream is underfit, meaning its current flow is too weak to have carved the valley it runs through.

The park was established in 1975, transforming former private ranch lands into a protected natural space as Calgary expanded. This decision helped preserve large green areas within the growing city.

The Environmental Learning Centre offers programs where visitors can discover local ecosystems and wildlife management through guided activities. These educational experiences help people understand how nature thrives within an urban setting.

The park has more than 100 kilometres of trails, over 60 kilometres of them paved, linking to Calgary's pathway system; the Trans Canada Trail crosses along the Bow River. A boat launch sits on the Bow River, and swimming is permitted at Sikome Lake. Seven pedestrian bridges were destroyed in the June 2005 floods, and the park reopened in September 2007 after new bridges and a redesigned pathway system.

Fish Creek Park is the second-largest urban park in Canada, after Rouge National Urban Park near Toronto and ahead of Pippy Park in St. John's. Its 13.48 km2 make it more than three times the size of Stanley Park in Vancouver. The park stretches 19 km from east to west, bordered on three sides by Calgary and on the west by Tsuu T'ina Nation land.
