Geregye (also Geregen) was the name of a gens (Latin for "clan"; nemzetség in Hungarian) in the Kingdom of Hungary in the 13th century. The Egervári family originated from this clan. The ancient lands of the kindred were in Vas County (today Gyanógeregye and Egervár).
Later Judge royal Paul Geregye's branch acquired possessions in Szolnok and Kraszna Counties, where tried to establish dominion independently from the king, alongside other prominent clans ( Abas, Gutkeleds, Kőszegis e.g.). However, Ladislaus IV of Hungary successfully defeated and eliminated their aspirations in 1277–1278, and this branch lost all of its political influence. Their lands and estates were governed by the Borsa clan following their downfall.
