Stampersgat is a village situated in the municipality of Halderberge, in the north-west of the North Brabant province in the Netherlands.

The village was first mentioned in 1639 as Stoutersgat, and means "mouth of the creek of the family Stamper".

The village used to be part of the municipality of Oud en Nieuw Gastel.

In 1993, the Province of North Brabant suggested a merger into Steenbergen.

The inhabitants of Stampersgat protested the decision and wanted to merge with Oudenbosch.
