Mersea Island is an island in Essex, England, in the Blackwater and Colne estuaries to the south-east of Colchester. Its name comes from the Old English word meresig, meaning "island of the pool" and thus is tautological. The island is split into two main areas, West Mersea and East Mersea, and connected to the mainland by the Strood, a causeway that can flood at high tide.

The River Blackwater is a river in Essex, England. It rises as the River Pant in the northwest of the county, just east of Saffron Walden, and flows in a generally southeast direction to Bocking, near Braintree, via Great Sampford and Great Bardfield. At Bocking, it becomes the River Blackwater, and veers east to flow past Bradwell Juxta Coggeshall and Coggeshall. It then veers south, flowing past Kelvedon and Witham, before reaching Maldon. There, it veers east again and empties into the Blackwater Estuary, which in turn meets the North Sea at Mersea Island.
