River Dun (River Test)

The River Dun is a river that flows through the counties of Wiltshire and Hampshire in England. The River Dun rises in Wiltshire to the south-east of Salisbury near West Grimstead, and flows east into Hampshire before joining the River Test at Kimbridge, ultimately draining to the Solent.

For the northern River Dun, see River Dun (River Kennet).
