The City Hall, Dublin (Irish: Halla na Cathrach, Baile Átha Cliath), originally the Royal Exchange, is a civic building in Dublin, Ireland. It was built between 1769 and 1779, to the designs of architect Thomas Cooley, and is a notable example of 18th-century architecture in the city. Originally used by the merchants of the city, it is today the formal seat of Dublin City Council.

City Hall is located on a slope on Dame Street, at the southern end of Parliament Street, on Dublin's southern side. It stands in front of part of Dublin Castle, the centre of British government in Ireland until 1922.
