This is a list of places in Ireland having standing links to local communities in other countries. In most cases, the association, especially when formalised by local government, is known as "town twinning" (though other terms, such as "partner towns" or "sister cities" are sometimes used instead), and while most of the places included are towns, the list also comprises villages, cities, districts, counties, etc. with similar links.
Sign posted at the entrance of Greystones, Co. Wicklow, Ireland, stating that the city is twinned with Holyhead, in Wales.
The list is arranged by province; and then by the county. It forms part of the larger list of twin towns and sister cities.
