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.

Bus Éireann route 450 (Dooagh-Westport-Louisburgh) operates several times a day in each direction, less often on Sundays.
