Tetouan (from the Berber Tiṭṭawin, Arabic: تطوان, Spanish: Tetuán, French: Tétouan) is a city in northern Morocco. The Berber name means literally "the eyes" and figuratively "the water springs". Tetouan is one of the two major ports of Morocco on the Mediterranean Sea. It lies a few miles south of the Strait of Gibraltar, and about 40 mi (60 km) E.S.E. of Tangier. In 2004 the city had 320,539 inhabitants (census figure). Tetouan's civil airport Sania Ramel Airport is located 6 km to the east.

Arabic is the official language but it is not used for everyday dialogue. The city has its own dialect, a particular citadin variant of non-hilalian Arabic which is distinct from Jebli Arabic. However, Jebli Arabic is predominant since people from the neighboring rural areas settled in the city during the 20th century rural flights.The use of Spanish and French is still widespread especially by the businessmen and intellectual elites^{[citation needed]}. Its main religion is Islam. A small Christian minority lives in the city.
