Blackrock (Irish: Na Creagacha Dubha), is a bustling seaside village just 4k to the south of Dundalk, County Louth, Ireland .

The view looking North over Dundalk Bay from the promenade toward the Cooley Mountains is impressive. The beach has a very gentle gradient and the sea retreats about 5km at low tide. It is a mixture of sand and mud flats, and is suitable for bathing, though with little water depth even at full tide.

It is also a fertile habitat for a variety of wader birds, including Brent geese and dunlins.

The sea is fronted by a lovely promenade graced by a sundial, the largest of any in a public place in Ireland. The front in Blackrock is becoming popular as a safe sail-boarding venue, and kite-surfing venue when the sea retreats.

Blackrock is the home of the Dundalk Golf Club, a magnificent 18 hole parkland course.
