The U2 Tower was a cancelled landmark skyscraper which was to be constructed in Dublin. The site chosen was in the South Docklands (SODO) campshires, at the corner of Sir John Rogerson's Quay and Britain Quay, by the confluence of the River Liffey, the River Dodder, and the Grand Canal. The design announced on 12 October 2007 was by Foster and Partners. Its height had been reported at 120 metres, "well over 120 metres", and 180 metres, any of which would have made it the tallest building on the island of Ireland. The building was planned to be an apartment building, with a recording studio owned by the rock group U2 in a "pod" at the top. Construction was to begin in 2008 and end in 2011, at a cost of €200m. In October 2008, the project was cancelled because of the economic downturn at the time. Proposals to revive the plan were reported in July 2013. However, they did not come to fruition and the 79-metre, 22-storey Capital Dock development has since been built on the site.

At the rear of the tower there are two entrances, one at ground level and another at wall-walk level.
