Gyöngyöstarján is a village in Heves County, Hungary, beside of the Tarján creek, under the Mátra mountain ranges.

North of the settlement was still a castle at that time, in the place of which only stone ramparts remain today.

From 1334 it was the property of Thomas Szécsényi, then in 1461, when the family died out, it was inherited by Albert Losonci and János Guthi Országh.

In the 18th century, the Haller family built a baroque-style church and parish, as well as a 542-meter-long wine cellar.

György Borhy built a hunting lodge north of the village in 1926, which is now an event center.
