Bir El Djir (Arabic: بئر الجير), formerly known as Arcole, is a town and commune in the Oran Province, Algeria. It is an eastern suburb of Oran, the province's capital. In 2009, it had a population of 171,883 people.

The name of the town is thought to come from the Arabic words بئر (bir) and جِير (jir), which together translate roughly as "spring [of] the lime", or "lime spring". During the French colonial period, the town was called Arcole, which referred to the Battle of Arcole.
