The General Post Office (GPO; Irish: Ard-Oifig an Phoist) in Dublin is the headquarters of the Irish Post Office, An Post, and Dublin's principal post office. Sited in the centre of O'Connell Street, the city's main thoroughfare, it is one of Ireland's most famous buildings, and was the last of the great Georgian public buildings erected in the capital.

The GPO was first located in a small building on the site of where the Commercial Buildings used to be (now the Central Bank building) off Dame Street, and was afterwards removed to a larger house opposite the Bank of Ireland building on College Green. On 6 January 1818, the new post-office in Sackville Street (now O'Connell Street) was opened for business. The foundation-stone of the building, which is built after a design of Francis Johnston, was laid by the Lord Lieutenant of Ireland, Charles Whitworth, 1st Earl Whitworth, on 12 August 1814, attended by the Post-Masters-General, Charles O'Neill, 1st Earl O'Neill and Laurence Parsons, 2nd Earl of Rosse. The structure was completed in the short space of three years for the sum of £50,000.

The front, which extends 67.1 metres (220 ft), has an Ionic portico (24.4 metres (80 ft) wide), of six fluted Ionic columns, 137.16 centimetres (54 inches) in diameter. The frieze of the entablature is highly enriched, and in the tympanum of the pediment were the royal arms until removed following restoration in the 1920s. On the acroteria of the pediment are three statues by John Smyth: when facing the building Mercury on the left, with his Caduceus and purse; Fidelity on the right, with a hound at her feet and a key held in her right hand (due to these features it is argued that the statue is in fact of Hecate); and Hibernia in the centre, resting on her spear and holding a harp. The entablature, with the exception of the architrave, is continued along the rest of the front; the frieze, however, is not decorated over the portico. A balustrade surmounts the cornice of the building, which is 15.2 metres (50 ft) from the ground.
