The River Coln is a river in Gloucestershire.
The Coln rises at Brockhampton to the east of Cheltenham, and flows in a south/south-easterly direction through the Cotswold Hills by way of Andoversford, Withington, Fossbridge, Bibury, Coln St Aldwyns and Fairford.
Extensive gravel pits that are now redundant, lying between Fairford and Lechlade, form the eastern component of the Cotswold Water Park, which is fed and drained by the Coln.
The river contains fish of many species, including brown trout and grayling.
