Anfa was the ancient toponym for Casablanca during the classical period. The city was founded by Berbers around the 10th century BC, with the Romans under Augustus later establishing the commercial port of "Anfus" in 15 BC. Anfa is now the name of a district in the oldest part of Casablanca, located in the Casablanca-Settat region of Morocco. The district covers an area of 37.5 square kilometres, and as of 2004 had 492,787 inhabitants.

Casablanca is the largest city in Morocco and the country's economic and business centre. Located on the Atlantic coast of the Chaouia plain in the central-western part of Morocco, the city has a population of about 3.71 million in the urban area, and over 4.27 million in Greater Casablanca, making it the most populous city in the Maghreb region, and the eighth-largest in the Arab world.
