Tunks Park Boat Ramp is a council-owned, two-lane concrete ramp located on Brothers Avenue, Cammeray/Northbridge, on Middle Harbour in Sydney, NSW.

The ramp and accompanying jetty are both in excellent condition and are suitable for use at all tides, though the ramp surface can be slippery at low tide. A pontoon with a dedicated kayak launch area is also available.

The site is accessed via a narrow, winding road. Parking is free but limited and fills quickly, particularly on weekends. The facility is lit and has a washdown area. A separate trailer parking area is available on site.
