Het Verdronken Land van Reimerswaal (translation: The Drowned Land of Reimerswaal) is an area of flood-covered land in Zeeland in the Netherlands between Noord Beveland and Bergen op Zoom.
The Oosterschelde formerly flowed along its east and north edges.
Verdronken is Dutch for "drowned", and Markizaat van Bergen op Zoom is the marquisate of Bergen op Zoom).
The Dutch land reclamation engineer and writer Vierlingh blamed the loss of that land on a landowner called the Lord of Lodijke neglecting a tidal creek which was scouring at every tide.
After the land was lost, the city of Reimerswaal survived on a small island for a while.
