List of tallest buildings in Ireland

This article is about the tallest habitable buildings in Ireland. For the tallest structures overall, see List of tallest structures in Ireland.

This is a list of the tallest habitable buildings on the island of Ireland (used for living and working in, as opposed to masts and churches). This includes both Northern Ireland in the United Kingdom, and the Republic of Ireland. The island of Ireland has relatively few tall buildings. The island's first tall building was Liberty Hall, built in 1965, which stands at 59.4 metres (195 ft). The current tallest habitable building on the island of Ireland is the Obel Tower in Belfast, Northern Ireland at 85 metres (279 ft).[1][2][3] The tallest storied building in the Republic of Ireland is College Square in Dublin, at about 82 metres (269 ft).[4][5][6]
