Julius (I) from the kindred Rátót (Hungarian: Rátót nembeli (I.) Gyula; died 1239) was a powerful Hungarian baron and landowner, who held several secular positions during the reign of kings Andrew II and Béla IV. He was the founder of the gens Rátót's economical and political power. He was the second son of Leustach Rátót, who served as voivode of Transylvania from 1176 to 1196. As Julius I had no descendants, his brother Rathold, ispán (comes) of Somogy County carried on the clan's name through his two sons.
