Hen Reedbeds is a 55 hectare nature reserve near the North Sea coast of the English county of Suffolk.

The reserve is located in the Blyth valley between Reydon and Blythburgh, approximately 2.5 miles (4.0 km) west of Southwold.

[5][6] It was specifically created to provide a range of freshwater habitats and is an important site for bitterns and marsh harriers within the UK.

[7] The reserve is seen as an example of the effective management of habitats in the face of coastal erosion and sea level rise along the Suffolk coast.

Way marked trails, some of which are wheelchair accessible, guide visitors around the site with a range of viewing platforms and hides.
