Kisnána is a village in Heves County, Hungary, beside of the Forrás creek in the Mátra mountain ranges.

The chapel of the later castle was built in the Romanesque style in the 12th century, and the village of Egyházasnána, was established around it.

The present church of St. Stephen the King was built in the 18th century in Baroque style.

During 1962-1966 the castle was excavated and turned into a museum, the most recent renovation being in 2010–2011, when several event halls were created.

The village's folk museum was opened in 1971 to showcase the traditions of the local Slovaks.
