The Provinces of Saudi Arabia, also known as Regions, (Arabic: مناطق المملكة العربية السعودية, romanized: Manāṭiq al-Mamlakat il-'Arabiyyat il-Sa'udiyyah), are the 13 first-level administrative divisions of the Kingdom of Saudi Arabia.^[1][2][3]

After the unification of Saudi Arabia, the kingdom was divided into seven provinces: the 'Asir Province, Al Hasa' Province, the Hejaz Province, the Najd Province, the Rub' al-Khali Province and the Shammar Province.^[1]

King Fahd bin Abdulaziz Al Saud issued Royal Order A/92 on March 2, 1992, known as Law of the Provinces,^[4] which provided for the division of the kingdom into 13 provinces. Subsequently, the five previous provinces were divided into thirteen regions, called provinces (manātiq), each governed by administrative bodies called the emirates of the provinces (imārāt al-manātiq). The provinces form the first-level administrative division of the Organization of the Kingdom of Saudi Arabia and are further divided into 136 governorates (muḥāfaẓāt), which are the second-level division,^[3] which are further subdivided into 1,347 municipal-level units (marakiz), and further subdivided into villages (qura) and neighborhoods (ahya).

Each province is governed by an Emir (Provincial Governor), who is assisted by the deputy emir, called nā'ib. The persons holding these positions are appointed by the King of Saudi Arabia. The emir is given the rank of minister, while the deputy emir is given the rank of excellence.^[3]
