Gob an Choire or Gob a' Choire (English name: Achill Sound), formerly anglicised as Gubacurra, is a Gaeltacht village in County Mayo, Ireland. It lies on the east coast of Achill Island and is the first settlement one reaches after crossing the Michael Davitt Bridge, a swing bridge that joins Achill Island to Corraun Peninsula on the mainland. In ancient times the southern entrance was guarded by Carrickkildavnet Castle. Achill Sound is also the name of the waterway separating Achill Island from the Irish mainland.
