Castle Eaton Bridge is a road bridge across the River Thames in England at Castle Eaton in Wiltshire. It carries a minor road between Cricklade, 4 miles to the southwest, and Kempsford 11⁄2 miles to the east.

The iron girder bridge with brick piers was built in 1893 with materials supplied by iron founders E Finch & Sons of Chepstow. It was described by Fred Thacker in 1920 "The present deplorable iron trough ... The Conservancy is often blamed for its hideousness; their responsibility amounts only to acquiescence; I understand the Swindon District Board was the actual artist". It was strengthened in 2001.

The bridge it replaced was of timber with stone piers and stone causeway.
