Urrea de Gaén is a municipality located in the province of Teruel, community of Aragon, Spain.

Urrea de Gaén has known human settlement at least since the Chalcolithic period (2100 BC), as evidenced by ruins and remains discovered in numerous excavations.

A long Muslim occupation and residence (from the eighth century to 1610) left its mark in the local architecture in the Moorish styling of the village.

The area was occupied by the Aragonese from the twelfth century, at the time of Ramon Berenguer IV and Petronila, becoming part of the Aragon defensive system.

After multiple marriages, lawsuits and swaps, in 1268 King James I created the Lordship of Híjar for his natural son Pedro Fernandez de Hijar.
