Áras an Uachtaráin, Presidential residence in Phoenix Park, Dublin, Ireland

Áras an Uachtaráin is a long white classical building with a grey slate roof in Phoenix Park, Dublin. Four round columns with plain capitals carry a triangular pediment with a dentil cornice, and a white balustrade runs across the base of the portico. Five white chimneys rise from the roofline, and a flagpole at its centre flies the green, white and orange flag.

The property began in 1751 as a private country house for Nathaniel Clements, the park ranger of Phoenix Park. From 1782 it was converted into the Viceregal Lodge and housed British viceroys until the first Irish president, Douglas Hyde, moved in during 1938.

The name Áras an Uachtaráin is Irish for "Residence of the President", given after the building was renamed from Viceregal Lodge. The Franciscini Corridor inside is lined with busts of past presidents, and new office-holders receive their seal of office here. The state drawing room is where Lord Spencer heard the victims' screams during the 1882 Phoenix Park Murders.

The residence stands off Chesterfield Avenue in Phoenix Park; its garden front portico can be seen from the main road through the park. Access to the house itself is by tour only, and visitors pass through security checks, so bring identification and arrive early. The state rooms open to visitors are few, among them the state drawing room, the dining rooms and the Franciscini Corridor lined with busts of past presidents.

The garden front portico, visible from Chesterfield Avenue, is said by some historians to have inspired James Hoban, the Irish architect of the White House; the porticoes there were added later by Benjamin Henry Latrobe. In 2011 Queen Elizabeth II planted an Irish oak sapling here.
