Tangier ( tan-JEER; Arabic: طنجة, romanized: Ṭanja; Berber languages: ⵟⴰⵏⵊⴰ, romanized: Ṭanjah) is a city in northwestern Morocco, on the coast of the Mediterranean Sea. The city is the capital of the Tanger-Tetouan-Al Hoceima region, as well as the Ṭanja-Aẓila Prefecture of Morocco.

Many civilisations and cultures have influenced the history of Tangier, starting from before the 10th century BCE. Starting as a strategic Berber town and then a Phoenician trading centre, Tangier has been a nexus for many cultures. In 1923, it became an international zone managed by colonial powers and became a destination for many European and American diplomats, spies, bohemians, writers and businessmen. That status came to an end with Moroccan independence, in phases between 1956 and 1960.

By the early 21st century, Tangier was undergoing rapid development and modernisation. Projects include tourism projects along the bay, a modern business district called Tangier City Centre, an airport terminal, and a football stadium. Tangier's economy is set to benefit greatly from the Tanger-Med port.
