Berowra Valley National Park, Protected wilderness area in northern Sydney, Australia

Berowra Valley National Park covers 3,884 hectares of the dissected Hornsby Plateau, where Hawkesbury Sandstone underlies most of the Berowra Creek catchment. Its boundaries run from Boundary Road at Pennant Hills south to Berowra Waters north, with the Pacific Motorway to the north-east and Galston Gorge to the west. The park holds fragments of Blue Gum High Forest, a wet sclerophyll community.

The park began in 1964 as Elouera Bushland Natural Park, a 640-hectare reserve. In 1987 it was gazetted as Reserve No. 100092 for public recreation and the study and preservation of native flora and fauna, a response to community concern over bushland development in Hornsby Shire. It became Berowra Valley Regional Park on 27 March 1998 and a national park in September 2012.

The name Berowra comes from Aboriginal language and refers to a place of many winds, reflecting traditional knowledge about local weather patterns. This connection between the landscape and natural phenomena is still visible in how the terrain shapes wind flow through the valleys and ridges.

The park features over 70 kilometers of walking tracks and fire trails with facilities at Crosslands Reserve for picnicking and rest. Visitors should prepare for uneven terrain and be ready for weather conditions that can change quickly in valleys and ridges.

On 27 January 2013 a man was found alive in the park after nine weeks lost in the bush. He survived one of Australia's worst heatwaves, with daytime temperatures above 45 degrees, on the water and food he had carried with him.
