The River Coln is a river in Gloucestershire, England. It rises to the north of Brockhampton, a village to the east of Cheltenham, and flows in a south/south-easterly direction through the Cotswold Hills via Andoversford, Withington, Fossebridge, Bibury, Coln St Aldwyns, Quenington and Fairford. It joins the River Thames to the south-west of Lechlade, near to the confluence with the Thames and Severn Canal.^[1]

Midway between Withington and Fossbridge the river passes Chedworth Roman Villa.

Extensive gravel pits between Fairford and Lechlade, now redundant, have been flooded to form the eastern component of the Cotswold Water Park. They are fed and drained by the Coln.^[2]

The river is host to many species of freshwater fish including brown trout and grayling.^[1]
