Andersey Island

Andersey Island is a 273-acre (110.5 ha) area of flood-meadow and former flood-meadow south-east of Abingdon Bridge, Abingdon-on-Thames, Oxfordshire, England, on the reach of the River Thames above Culham Lock. It is in Culham parish, but has close links with Abingdon-on-Thames, which lies directly across the (main branch of the) Thames. It is the second-largest island in the non-tidal part of the Thames. (The largest is the recently created island between the Thames and the engineered Jubilee River channel, which encloses Dorney and Eton.)

The A415 road, the main road leading south from Abingdon, crosses the island on a causeway. The Thames Path also crosses the island.
