The Hawkesbury River, or Hawkesbury-Nepean River, is a river located northwest of Sydney, New South Wales, Australia. The Hawkesbury River and its associated main tributary, the Nepean River, almost encircle the metropolitan region of Sydney. The Hawkesbury River has its origin at the confluence of the Nepean River and the Grose River, to the north of Penrith and travels for approximately 120 kilometres (75 mi) in a north–easterly and then a south–easterly direction to its mouth at Broken Bay, about 15 kilometres (9.3 mi) from the Tasman Sea. The Hawkesbury River is the main tributary of Broken Bay. Secondary tributaries include Brisbane Water and Pittwater, which, together with the Hawkesbury River, flow into Broken Bay and thence into the Tasman Sea north of Barrenjoey Head. The total catchment area of the river is approximately 21,624 square kilometres (8,349 sq mi) and the area is generally administered by the Hawkesbury–Nepean Catchment Management Authority.
