The '''Tank Stream''' is a heritage-listed former fresh water [[tributary]] of [[Sydney Cove]] and now tunnel and watercourse located in the [[Sydney central business district]], in the [[City of Sydney]] local government area of [[New South Wales]], Australia. The Tank Stream was the fresh water supply for the fledgling [[Colonisation of Australia|colony of New South Wales]] in the late 18th century. Today it is little more than a storm water drain. It originated from a swamp to the west of present-day [[Hyde Park, Sydney|Hyde Park]] and at high tide entered Sydney Cove at what is now the intersection of [[Bridge Street, Sydney|Bridge]] and [[Pitt Street]]s in the Sydney central business district. The catchment was {{convert|65|ha|acre|0}}, corresponding roughly the size of the Sydney central business district. It was added to the [[New South Wales State Heritage Register]] on 2 April 1999.<ref name=nswshr-636>{{cite NSW SHR|5045604|Tank Stream|hr=00636|fn=S90/04382; 10/01313|access-date=13 October 2018}}</ref>
