Lodmoor is a Site of Special Scientific Interest (SSSI), RSPB reserve and country park in Dorset, England.

The country park features a visitor centre, model railway and pitch and putt golf course.

The construction of a sea wall in the twentieth century has prevented regular tidal incursions, although freshwater flooding is still an occurrence, especially in winter.

[2] The SSSI is composed of reed bed, salt marsh, wet grassland and open water, and is separated from Weymouth Bay by Greenhill beach and the B3155 road.

[1] Part of the area designated as Lodmoor SSSI is owned by the Royal Society for the Protection of Birds.
