Rátót (Ráthold or Rátold) was the name of a gens (Latin for "clan"; nemzetség in Hungarian) in the Kingdom of Hungary.

The Lorántffy, Kakas de Kaza, Feledi, Putnoki, Jolsvai, Kakas, Gyulaffy, Elefánti, Paksi, Pásztói, Kaplai, Ráday and Tari families were originate from the Genus Rátót.

The ancestors of the Rátold family came to Hungary from the town of Caserta in the province of Puglia, according to Simon Kézai and other chronicles following him.

The divergence of opinions about the origin of the Rátót genus is caused by the fact that Simon Kézai exchanged the place of origin of the Rátót genus (Swabia) with the Hontpázmány's (Apulia), and it is seldom possible to reach a stable conclusion from an erroneous starting point.

In József Csoma's „Magyar nemzetségi címerek” (Coat of Arms of Hungarian Genera) (Hungarian scientific Academy, Budapest, 1904), gets stuck in the fact that the chronicles derive the Ratholds from Apulia.
