Fisherrow Harbour is a small working harbour located in Musselburgh, East Lothian, on the southern shore of the Firth of Forth. Managed by East Lothian Council, it serves primarily leisure craft, with around 40–50 boats typically berthed there.

The harbour sits near the mouth of the Esk and is a noted spot for birdwatching, with views across to Fife and Edinburgh visible from the harbour wall.

The harbour serves as a waypoint on cycling and walking routes in the area, including the Brunstane Burn Walkway. It is accessible by bus and rail from Edinburgh, with Musselburgh train station a short distance away. Free parking is available on site.
