The Lane Cove River, a northern tributary of the Parramatta River, is a tide-dominated, drowned valley estuary[1] west of Sydney Harbour, located in Sydney, New South Wales, Australia. The river winds through a bushland valley and joins Parramatta River at Greenwich and Woolwich, where together they form an arm of Sydney Harbour, and serves as a border along with Middle Harbour separating Sydney's North Shore.
