This is a list of the tallest buildings on the island of Ireland. The island of Ireland remains one of the world's lowest occupiers of skyscrapers and tall buildings. As of 2017, a number of proposals have been made to change this, with developments proposed for Limerick,CorkGalway, and Dublin. The island's first tall building was Liberty Hall, built in 1965 and stands at 59.4m (154 feet). The current tallest building on the island is the Obel Tower in Belfast, which was completed in 2010, with the tallest in the Republic of Ireland being The Elysian in Cork, which finished in 2008. Capital Dock in Dublin, standing at 78 metres, is expected to replace The Elysian as the Republic's tallest building when completed in 2017, also becoming the third tallest on the island. It is located in Dublin Docklands and includes offices, residential elements and retail.
Those in Northern Ireland are denoted by a light blue background. The remainder are in the Republic of Ireland.
