# List of family seats of Irish nobility

This is an incomplete index of the current and historical principal family seats of clans, peers and landed gentry families in Ireland. Most of the houses belonged to the Old English and Anglo-Irish aristocracy, and many of those located in the present Republic of Ireland were abandoned, sold or destroyed following the Irish War of Independence and Irish Civil War of the early 1920s.
