El Tor, also romanized as Al-Tur and At-Tur and known as Tur Sinai, formerly Raithu, is a small city and the capital of the South Sinai Governorate of Egypt. The name of the city comes from the Arabic term for the mountain where the prophet Moses is believed to have received the Tablets of the Law from God; this mountain is designated Jabal Al Tor.

South Sinai Governorate is the least populated governorate of Egypt. It is located in the east of the country, encompassing the southern half of the Sinai Peninsula. Saint Catherine's Monastery, an Eastern Orthodox Church monastery and UNESCO World Heritage Site of world renown, is located in the central part of the governorate.
