This is a list of the marine bivalves recorded from Ireland. It is part of the List of marine molluscs of Ireland. The list includes species from the continental margin (200–500m), bathyal zone (500–2000m), and abyssal zone (2000–4000m), in the Rockall Basin, Porcupine Seabight, and Celtic Sea.
Taxonomy follows Taxonomy of the Bivalvia (Bouchet, Rocroi, Bieler, Carter & Coan, 2010).
