Gyula III, also Iula or Gyula the Younger, Geula or Gyla, was an early medieval ruler in Transylvania. Around 1003, he and his family were attacked, dispossessed and captured by King Stephen I of Hungary (1000/1001-1038). The name "Gyula" was also a title, the second highest rank in Hungarian tribal confederation.

Transylvania is a historical and cultural region in Central Europe, encompassing central Romania. To the east and south its natural border is the Carpathian Mountains and to the west the Apuseni Mountains. Broader definitions of Transylvania also include the western and northwestern Romanian regions of Crișana and Maramureș, and occasionally Banat. Historical Transylvania also includes small parts of neighbouring Western Moldavia and even a small part of south-western neighbouring Bukovina to its north east. The capital of the region is Cluj-Napoca.
