The Sanjak of Alexandretta (Arabic: لواء الإسكندرونة, romanized: Liwa' Al-Iskandarūna; Turkish: İskenderun Sancağı; French: Sandjak d'Alexandrette) was a sanjak of the Mandate of Syria composed of two qadaas of the former Aleppo Vilayet (Alexandretta and Antioch, now İskenderun and Antakya). It became autonomous under Article 7 of the 1921 Treaty of Ankara: "A special administrative regime shall be established for the district of Alexandretta. The Turkish inhabitants of this district shall enjoy facility for their cultural development. The Turkish language shall have official recognition".
In 1923, Alexandretta was attached to the State of Aleppo, and in 1925, it was attached to the combined State of Syria, with a sort of federal administrative status termed régime spécial.
