The Bertha de Felsőőr family (or Felső-Eőr in the Middle Ages) is a still existing Hungarian noble family from Vas county, who moved to Sopron and Zala counties also.

The family received noble title in exchange for his service as a border guard at Oberwart (Felsőőr).

The family's nobility was confirmed on July 1, 1327, by Charles I.
