Vállaj is a village in Szabolcs-Szatmár-Bereg county, in the Northern Great Plain region of eastern Hungary.

In 1423 the Báthorians won a royal gift to him, and thus became part of the Ossetian estate, sharing his fate.

As early as 1712, Count Sándor Károlyi, the landlord of the region, applied to the Viennese court to bring German settlers.

Today, the name Ágerdő refers to a vineyard and a farm settlement on the eastern border of Vállaj, close to Börvely in Romania.
