The Eparchy of Nyíregyháza is an eparchy (diocese) of the Hungarian Greek Catholic Church, an Eastern Catholic church which uses the Byzantine Rite in the Hungarian language.

It's cathedral church is Szent Miklós Görögkatolikus székesegyház which is situated in the city of Nyíregyháza, Hungary. It is a suffragan diocese of the Archeparchy of Hajdúdorog, a Metropolitanate sui juris and the Greek Catholics in Hungary' only province.

The eparchy was erected by the Holy See on 20 March 2015, on territory split off from the then Eparchy of Hajdúdorog, which at the same time was elevated to an Archeparchy and became Nyíregyházai's Metropolitan, the other suffragan being the former Apostolic Exarchate of Miskolc, which was simultaneously promoted to Eparchy.
