Bagossy de Bagos et Kaplony (or Bagosi) was a Hungarian noble family from the kindred of Kaplon.
His son, Simon Ördög, is mentioned in contemporary sources from 1264.
Simon had four sons: Andrew, the forefather of the Károlyi family, Endus, Mikó and Peter.
In 1354, Louis I of Hungary granted them the right of blood court.
