St. Nicholas Church, belonging to the Budapest and Hungarian Diocese of the Moscow Patriarchate, is located in the town of Dyondyosh, Hungary.

The church was built between 1809 and 1811. In 1908, it suffered significant damage from a fire, and it was not until 1946 that the destroyed bell tower spire was restored.

The parish, which had long been considered extinct, was revived after 1945, and the church reopened its doors to the Orthodox community of Dyondyosh, which numbered about 70 people. After a period of stagnation in the 1970s and 1980s, when there was no permanent priest, a new quiet revival began in 1999. Significant renovations were carried out both inside and outside the building from 1999 to 2001, as well as in 2005.

On July 4, 2001, the church was served by Archbishop Paul (Ponomaryov) of Vienna and Budapest, Bishop Daniel (Krshtich) of Budim, and Bishop Sophrony (Drinchets), along with a large number of clergy.

In the following years, the parish repeatedly organized youth and children's camps. The Divine Liturgy is held once a month until a new permanent priest is appointed.
