Frampton Marsh is a nature reserve in Lincolnshire, England.

The reserve is situated on the coast of The Wash, 4 miles from the town of Boston, between the outfalls of the Rivers Welland and Witham (covering an area of mature salt marsh known as The Scalp), and near the village of Frampton in a area known as the “Fosdyke Wash”.

Species which can be regularly observed here include pied avocet, common redshank and Eurasian curlew.

These have included a black-winged stilt, broad-billed sandpiper and Wilson's phalarope during 2015[2] and a lesser yellowlegs during 2014.

[3] The site was also the location of the first nesting attempt by a glossy ibis in the UK.
