Saudi Arabia, officially known as the Kingdom of Saudi Arabia (KSA), is an Arab sovereign state in Western Asia constituting the bulk of the Arabian Peninsula. With a land area of approximately 2,150,000 km2 (830,000 sq mi), Saudi Arabia is geographically the fifth-largest state in Asia and second-largest state in the Arab world after Algeria. Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south. It is separated from Israel and Egypt by the Gulf of Aqaba. It is the only nation with both a Red Sea coast and a Persian Gulf coast, and most of its terrain consists of arid desert or barren landforms.

The area of modern-day Saudi Arabia formerly consisted of four distinct regions: Hejaz, Najd, and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia ('Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud. He united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. Saudi Arabia has since been an absolute monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultraconservative Wahhabi religious movement within Sunni Islam has been called "the predominant feature of Saudi culture", with its global spread largely financed by the oil and gas trade. Saudi Arabia is sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca), and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. The state has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners. The state's official language is Arabic.
Saudi Arabia occupies about 80% of the Arabian Peninsula (the world's largest peninsula), lying between latitudes 16° and 33° N, and longitudes 34° and 56° E. Because the country's southern borders with the United Arab Emirates and Oman are not precisely marked, the exact size of the country is undefined. The CIA World Factbook estimates 2,149,690 km2 (830,000 sq mi) and lists Saudi Arabia as the world's 13th largest state. It is geographically the largest country in the Arabian Plate.
Saudi Arabia's geography is dominated by the Arabian Desert and associated semi-desert and shrubland (see satellite image). It is, in fact, a number of linked deserts and includes the 647,500 km2 (250,001 sq mi) Rub' al Khali ("Empty Quarter") in the southern part of the country, the world's largest contiguous sand desert. There are virtually no rivers or lakes in the country, but wadis are numerous. The few fertile areas are to be found in the alluvial deposits in wadis, basins, and oases. The main topographical feature is the central plateau which rises abruptly from the Red Sea and gradually descends into the Nejd and toward the Persian Gulf. On the Red Sea coast, there is a narrow coastal plain, known as the Tihamah parallel to which runs an imposing escarpment. The southwest province of Asir is mountainous, and contains the 3,133 m (10,279 ft) Mount Sawda, which is the highest point in the country.
Except for the southwestern province of Asir, Saudi Arabia has a desert climate with extremely high day-time temperatures and a sharp temperature drop at night. Average summer temperatures are around 113 °F (45 °C), but can be as high as 129 °F (54 °C). In the winter the temperature rarely drops below 32 °F (0 °C). In the spring and autumn the heat is temperate, temperatures average around 84 °F (29 °C). Annual rainfall is extremely low. The Asir region differs in that it is influenced by the Indian Ocean monsoons, usually occurring between October and March. An average of 300 mm (12 in) of rainfall occurs during this period, that is about 60% of the annual precipitation.
Animal life includes Arabian wolves, striped hyenas, mongooses, baboons, hares, sand rats, and jerboas. Larger animals such as gazelles, oryx, and leopards were relatively numerous until the 1950s, when hunting from motor vehicles reduced these animals almost to extinction. Birds include falcons (which are caught and trained for hunting), eagles, hawks, vultures, sandgrouse and bulbuls. There are several species of snakes, many of which are venomous, and numerous types of lizards. There is a wide variety of marine life in the Persian Gulf. Domesticated animals include Arabian camels or dromedaries, sheep, goats, donkeys, and chickens. Reflecting the country's desert conditions, Saudi Arabia's plant life mostly consists of small herbs and shrubs requiring little water. There are a few small areas of grass and trees in southern Asir. The date palm (Phoenix dactylifera) is widespread.
