context_page_description: This list of the non-marine molluscs of Ireland comprises 165 species of non-marine molluscs which have been recorded as part of the fauna of Ireland. These are terrestrial and aquatic gastropods, and bivalves; the list does not include species of molluscs which are considered to be fully marine.
  In other words: this list includes land snails and slugs, and freshwater and brackish water snails. It also includes freshwater mussels and freshwater clams, including some that can tolerate brackish water. Molluscs that are fully adapted to live in the sea are not included here.
  Ireland is an island in the northeastern Atlantic. It consists of the Republic of Ireland, also known simply as Ireland, and Northern Ireland, which is part of the United Kingdom.
  The mollusc fauna of the island of Ireland has not been as thoroughly researched as that of the island of Great Britain, and therefore it is possible that some uncommon and local species may, as yet, have been overlooked. Even so, it seems that the non-marine molluscan fauna of Ireland is a smaller fauna than that of Great Britain.
  This list is of land and freshwater molluscs only.
