An island on the Atlantic approaches has always taken ships. Here are 55 of the best-documented wrecks on its coast, in order, and what the national inventory says about the rest.
The National Monuments Service keeps a record of every known wreck in the Republic's waters. By century of loss:

The National Monuments Service's Wreck Inventory of Ireland holds 17,981 records for the Republic's waters alone, most of them from the 1800s. It records known losses; not every one has been found on the seabed.
Among the worst by lives lost: the Armada wrecks at Streedagh in 1588, the sinking of the Lusitania off the Old Head of Kinsale on 7 May 1915, with about 1,198 dead, and the RMS Leinster, torpedoed off the Kish on 10 October 1918, with at least 564.
Storms in autumn 1588 drove many Armada ships onto the west and north coasts. At Streedagh in Sligo three large ships were wrecked together; the survivor Francisco de Cuéllar wrote that over a thousand drowned.
The wrecks listed are those with their own article in Wikipedia's Shipwrecks of Ireland ↗ and Northern Ireland categories, lost at or near the coast; each summary and figure is from that article, and a county is given only where the article places the loss off a named place in it. Losses far out to sea are left out.
