Cregg Mill is a converted 18th century watermill located near Corrandulla village in County Galway, Ireland, approximately 9 miles 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 situated on the Cregg River which rises from a spring a half mile to the north, and flows into Lough Corrib.
