An Post Museum, Postal museum in North City, Dublin, Ireland.

The An Post Museum was a small museum in the General Post Office on O'Connell Street, Dublin, open from 28 July 2010 to 30 May 2015. It displayed Irish stamps and philatelic information, a scale model of the GPO, audio-visual presentations, An Post's copy of the 1916 Proclamation and a Pepper's ghost dramatisation of staff on duty on Easter Monday 1916.

The An Post Museum opened on 28 July 2010 in the General Post Office, the headquarters of the 1916 Easter Rising. It closed on 30 May 2015 and was replaced on 29 March 2016 by the GPO Museum, a visitor centre with a permanent exhibition for the centenary of the Rising.

The museum holds memories of the postal service's role during the 1916 Easter Rising, as you walk through displays about staff involvement in that event. The collections show how this building became central to a turning point in Irish history and how people experienced it during those days.

The An Post Museum closed on 30 May 2015, so there is no museum to visit in the GPO basement today. Its successor, the GPO Museum, opened on 29 March 2016 in the same General Post Office building on O'Connell Street. Much of the old museum's information and audio-visual material remains available on the An Post website.

The An Post Museum ran only from 28 July 2010 to 30 May 2015, then closed to make way for a visitor centre marking the centenary of the 1916 Easter Rising. Its successor, the GPO Museum, opened on 29 March 2016 and covers the Easter Rising, the War of Independence, the Civil War and the Northern Ireland peace process.
