This is a list of the Annelida recorded from Ireland. In Ireland the number of species is:
Taxonomy Here the leeches and oligochaetes are placed together in the Class Clitellata. The marine Polychaeta are ranked as a Class. These groups (and the Annelida) may be monophyletic, paraphyletic or polyphyletic. (Rouse and Pleijel, 2001).
