Glengad, also known as Dooncarton (), is a large townland on the northwestern shore of Sruwaddacon Bay. Its name is derived from willows ("gads") from the Cromwellian period when the native Irish were sent "to hell or to Connaught". The settlers who came to Glengad brought the craft of basket weaving, planting willows in wet ground; willows have grown in the townland's streams ever since. It is a linear village, with houses and farms along the main road. The land was divided by the Irish Land Commission during the early 20th century; each farm is a narrow strip running from the mountain to the sea, a remnant of the rundale system of land division seen in many areas of the parish. Glengad is the hub of much of the Corrib gas controversy.
