Mariahout is a village located in the province of North Brabant in the south of the Netherlands, about 20 kilometers northeast of Eindhoven.

Mariahout has a population of about 1700 and is the smallest village of the municipality of Laarbeek.

From 1920 onwards, the heath land in the western part of the municipality of Lieshout was cultivated.

Since then many new farmsteads were built that, together with an existing settlement, formed a new village community.

This name is a contraction of Maria, the patron saint of the new parish, and Lieshout.
