Blackhead Lighthouse is a listed lighthouse built at the turn of the 20th century, near Whitehead in County Antrim, Northern Ireland. It marks the very northern end of Belfast Lough where it opens out into the North Channel that separates Northern Ireland and Scotland.
The active lighthouse is managed by the Commissioners of Irish Lights, where it is named as the Blackhead Antrim Lighthouse to distinguish it from the more modern Blackhead lighthouse in County Clare.
