Burton Mere Wetlands is a nature reserve on the Dee Estuary straddling the border between Cheshire, England and Flintshire, Wales. It is run by the Royal Society for the Protection of Birds (RSPB) and incorporates the older Inner Marsh Farm reserve. It lies near the village of Burton, about 3 kilometres (1.9 mi) south of Neston. It has all been developed by the RSPB and includes a large area of mixed wetland habitats, bluebell woodlands, and arable fields all managed to attract wildlife.
