Read's Island is an island situated just outside the Ancholme sluice, on the Humber Estuary in England. The Lincolnshire Trust suggest it is an artificial island, and a report from 1979 says that it was reclaimed. However, the site was for many years a large sandbank going by the name of "Old Warp" and is shown on the 1734 Customs Map of the Humber where Read's Island now lays, and extending further downstream.
