Dabas (German: Dabotz) is a town in Pest County, Hungary, and the center of a microregion.

The inhabitants of Upper-Dabas were catholic Hungarian serfs, Lower-Dabas was the centre of the lower nobility (especially the famous and populous Halász family), Sári (Šari) was populated by catholic Slovak colonists and Gyón by Reformed Hungarians and Evangelical Slovaks.

In the 19th century the nobility of Lower Dabas built several Neoclassical mansions – these are the main attractions of the town today.

In the 1970s Dabas was urbanised and a modern town centre was built with a court house, public school, office blocks and a big department store.

The most important of them is the big Neoclassical mansion of Móric Halász in Gyón and the Casino of the Nobles in Dabas.
