Breezanddijk (West Frisian: Breesândyk) is a small community that lies near the midpoint of the Afsluitdijk, part of the A7 motorway, in the Netherlands.

It is located on a former artificial island which was created during the construction of the dam, and it belongs to the municipality of Súdwest-Fryslân, in Friesland province.

The construction of the Afsluitdijk started at four points: two on both sides of the mainland and on two specially made construction-islands (Kornwerderzand and Breezanddijk) along the line of the future dyke.

There are about 40-50 buildings, most of which are bunkhouses that were built for the workers employed during the construction of the Afsluitdijk.

Today, it has a population of only four people living on a houseboat and its sole commercial establishment is a Esso gas station for travelers upon the dike.
