Calcot Mill is an historic former watermill on the Holy Brook, a channel of the River Kennet in the English county of Berkshire. The mill is situated in the civil parish of Holybrook and to the south of Calcot, a suburb of Reading.
The mill originally belonged to Reading Abbey, whose monks are believed to have created the Holy Brook as a water supply to this and other mills owned by them.
