Portmuck
Portmuck is a townland of 235 acres in County Antrim, Northern Ireland. It is situated in the civil parish of Islandmagee and the historic barony of Belfast Lower.
The townland has given its name to a little island just off the coast called Isle of Muck, which is a nature reserve.
In 2025, puffins were found to be nesting on the Isle of Muck for the first time in 25 years.
