Map - Makkah Province (Mecca Region)

The Mecca Province (مِنْطَقَة مَكَّة '), also known as the Mecca Region''', is one of the 13 provinces of Saudi Arabia. It is the third-largest province by area at 153,128 km² and the most populous with a population of 8,557,766 as of 2017, of which 4,041,189 were foreign nationals and 4,516,577 were Saudis. It is located in the historic Hejaz region, and has an extended coastline on the Red Sea. Its capital is Mecca, the holiest city in Islam, and its largest city is Jeddah, which is Saudi Arabia's main port city. The province accounts for 26.29% of the population of Saudi Arabia and is named after the holy city of Mecca.

Historically, the area was inhabited by the Quraysh, the Banu Kinanah and the Thaqif, among other tribes. Part of the Hejaz region, the province has seen several exchanges of power between many Islamic realms within a short period of time. The province gains its significance as it contains the city of Mecca, the birthplace of Muhammad, and several other historic Islamic sites, such as the village of Hudaybiyyah, where the Treaty of Hudaybiyyah is said to have been agreed upon. More recently, the province was modernized under the Ottoman Empire and the Kingdom of Saudi Arabia after the oil boom. Most of the population is concentrated in three cities: Jeddah, Mecca and Ta'if. Jeddah is the largest city in the province and the second-largest in Saudi Arabia with an estimated population of 2,867,446 as of 2020. Mecca is the second-largest city in the province and third-largest in the kingdom at 1,323,624. After the city of Ta'if at third place, Rabigh, Shafa, Turbah and Jumum are other populous cities and towns in the region. The region receives Muslim pilgrims of the Umrah and the Hajj around the year and its population increases by up to 2 million during the Hajj. It has approximately 700 km of coastline on the Red Sea and hosts oil refineries in Rabigh, port and oil export facilities in Jeddah, the King Abdullah University of Science and Technology and the King Abdullah Economic City. The province also hosts part of the Haramain high-speed railway line, which is Saudi Arabia's first and only high-speed railway line.

The province is divided into 11 governorates, of which 5 have been classified Category A and the rest, Category B, with Mecca serving as the administrative headquarters and capital of the province. It is governed by an Emir, translated as Governor from Arabic, who is assisted by the Deputy Governor, both appointed by the King of Saudi Arabia. The current emir is Khalid bin Faisal Al Saud, who has held the position for a second term since 2015.

Ancient Mecca was an oasis on the old caravan trade route that linked the Mediterranean world with South Arabia, East Africa, and South Asia. The town was located about midway between Maʾrib in the south and Petra in the north, and it gradually developed by Roman and Byzantine times into an important trade and religious centre. Ptolemy's inclusion of Macoraba, a city of the Arabian interior, in his Guide to Geography was long held to show that Mecca was known to the Hellenistic world. Since the late 20th century, however, some scholarship has called the identification of Macoraba with Mecca into question.

According to Islamic tradition, Abraham and Ishmael, his son by Hagar, built the Kaʿbah as the house of God. The central point of pilgrimage in Mecca before the advent of Islam in the 7th century, the cube-shaped stone building has been destroyed and rebuilt several times. During pre-Islamic times the region was ruled by a series of Yemeni tribes. Under the Quraysh it became a type of city-state, with strong commercial links to the rest of Arabia, Ethiopia, and Europe. Mecca became a place for trade, for pilgrimage, and for tribal gatherings. The city of Jeddah is believed to have been a fishing hamlet occupied by early Yemeni tribes. The region has held significant religious importance greatly increased with the expeditions of Muhammad in the early 7th century. As the ancient caravan route fell into decline, Mecca lost its commercial significance and has since lived mainly on the proceeds from the annual pilgrimages and the gifts of Muslim rulers.

The city of Mecca was sacked by the Umayyad general al-Ḥajjāj ibn Yūsuf, and thereafter the city, and at the time, the region, acknowledged the power of the Umayyad caliphate at Damascus and, following the eclipse of that dynasty, of the ʿAbbāsid caliphate of Baghdad. The city suffered great indignity at the hands of the Shīʿite Qarmatians in 930 when that sect's leader Ṭāhir Sulaymān pillaged Mecca and carried off the Black Stone from the Kaʿbah. Beginning in the mid-10th century, the rulers of the city were chosen from the sharifs, or descendants of Muhammad, who retained a stronghold on the surrounding region while often paying homage to stronger political entities. The ability of the sharifs, originally moderate Shīʿites, to adapt to the changing political and religious climate ensured their preeminence in local affairs for the next 1,000 years. In 1269, the region came under the control of the Egyptian Mamlūk sultans. In 1517, dominion over the area passed to the Ottoman Empire, with its capital in Constantinople (now Istanbul). With the Ottoman collapse after World War I, control of Mecca was contested between the sharifs and the House of Saʿūd of central Arabia, adherents to an austere, puritanical form of Islam known as Wahhābism. King Ibn Saʿūd conquered the region in 1925, and the region of Mecca became a province of the Kingdom of Saudi Arabia and the city became the capital of the province.

The region underwent extensive economic development as Saudi Arabia's petroleum resources were exploited after World War II, and the number of yearly pilgrims to Mecca has increased significantly.
