Cregg Mill is a converted 18th-century watermill in the townland of Cregg, near Corrandulla village in County Galway, Ireland, approximately 9 miles (14 km) from Galway City. The mill serviced the local area, including neighbouring Cregg Castle, and served as a feeding centre for the poor of Corrandulla during the Great Famine. An advertisement in the early twentieth century shows that wheat, rye, corn, oats, and barley were kiln-dried and ground there. The mill is on the Cregg River, which rises from a spring a half mile to the north and flows into Lough Corrib.
