Portballintrae (from Irish Port Bhaile an Trá, meaning 'port of the beach settlement') is a small seaside village in County Antrim, Northern Ireland.

Between 1967 and April 1968 a team of Belgian divers (including Robert Sténuit, the world's first aquanaut), located the remains of the wreck of the Girona off the coast of Portballintrae and brought up the greatest find of Spanish Armada treasure salvaged up until that time.

The ruins of Dunluce Castle sit on the edge of a cliff between Portballintrae and Portrush.

[citation needed] The Giant's Causeway Tramway runs through the sand dunes above the largest beach in Portballintrae, commonly known as Runkerry Strand, and Bushfoot Golf Club.

[5] Portballintrae is classified as a small village or hamlet by the NI Statistics and Research Agency (NISRA) (i.e. with population between 500 and 1,000 people).
