Stampersplaat is an anchorage and access point on the Grevelingenmeer, the large saltwater lake in the Zeeland delta of the Netherlands formed by the Delta Works closures of 1965 and 1971.

It lies in the eastern section of the lake, where the narrower geography provides good shelter from southwesterly winds, making it one of the more popular anchorages on the Grevelingenmeer in those conditions.

The site has dedicated jetties capable of accommodating vessels over 15 meters in length, which are required to moor here rather than at smaller jetties elsewhere on the lake.

The broader Grevelingenmeer is well regarded for diving, with reefs and wrecks that have developed since the lake's closure, offering visibility of up to 8–10 meters.
