Orange is a commune in the Vaucluse department in the Provence-Alpes-Côte d'Azur region in southeastern France. It has a primarily agricultural economy. It is located about 21 km north of Avignon.

The town is renowned for its Roman architecture and its Roman theatre is described as the most impressive still existing in Europe. The fine Triumphal Arch of Orange is often said to date from the time of Augustus or Tiberius, but is probably much later, perhaps Severan.[2] The arch, theatre and surroundings were listed in 1981 by UNESCO as a World Heritage Site. The Musée (Museum) displays the biggest (7.56 x 5.90 m) cadastral Roman maps ever recovered, etched on marble. They cover the area between Orange, Nîmes and Montélimar.
