Iron Cove is a bay on the Parramatta River, in the inner-west of Sydney, in the state of New South Wales, Australia.

It is surrounded by the suburbs of Birchgrove, Balmain, Rozelle, Lilyfield, Haberfield, Five Dock, Rodd Point, Russell Lea and Drummoyne.

The bay extends from Longnose Point to the south-west and is fed by the Hawthorne Canal and the Iron Cove Creek.

On the 1822 survey map of Port Jackson (Sydney Harbour) by John Septimus Roe, Lieut.

Stephensen suggests that the name is derived from the iron shackles worn by convicts from Cockatoo Island who were forced to work in the area around the bay from 1839.

A proposal has been put forward for a water filtration device to be installed at Iron Cove Creek.
