Many cadet members intermarry within the Al Saud to reestablish their lineage and continue to wield influence in the government. Members of the cadet branches hold high and influential positions in government though they are not in the line of succession to the Saudi throne. Al Saud's other family branches like Saud Al Kabir, the Al Jiluwi, the Al Thunayan, the Al Mishari and the Al Farhan are called cadet branches. The surname "Al Saud" is carried by any descendant of Muhammad bin Saud or his three brothers Farhan, Thunayyan, and Mishari. In the case of the Al Saud, the ancestor is Saud ibn Muhammad ibn Muqrin, the father of the dynasty's 18th century founder Muhammad bin Saud (Muhammad, son of Saud). House of Saud is a translation of Al Saud, an Arabic dynastic name formed by adding the word Al (meaning "family of" or "House of") to the personal name of an ancestor.

The king-appointed cabinet includes more members of the royal family. The monarchy was hereditary by agnatic seniority until 2006, when a royal decree provided that future Saudi kings are to be elected by a committee of Saudi princes. In 2017, Muhammad bin Nayef was replaced by Mohammad bin Salman, King Salman's son, as the crown prince after an approval by the Allegiance Council with 31 out of 34 votes.

King Salman, who reigns currently, first replaced the next crown prince, his brother Muqrin, with his nephew Muhammad bin Nayef. The succession to the Saudi Arabian throne was designed to pass from one son of the first king, Abdulaziz, to another. The family has had conflicts with the Ottoman Empire, the Sharif of Mecca, the Al Rashid family of Ha'il and their vassal houses in Najd, numerous Islamist groups both inside and outside Saudi Arabia and Shia minority in Saudi Arabia. The House of Saud has had three phases: the Emirate of Diriyah, the First Saudi State (1727–1818), marked by the expansion of Salafism the Emirate of Nejd, the Second Saudi State (1824–1891), marked with continuous infighting and the Third Saudi State (1902–present), which evolved into the Kingdom of Saudi Arabia in 1932 and now wields considerable influence in the Middle East. This figure includes the market capitalization of Saudi Aramco, the state oil and gas company, and its vast assets in fossil fuel reserves.

Some estimates of the royal family's wealth measure their net worth at $1.4 trillion. The family in total is estimated to comprise some 15,000 members however, the majority of power, influence and wealth is possessed by a group of about 2,000 of them. The most influential position of the royal family is the King of Saudi Arabia, an absolute monarch. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi state (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Abdulaziz bin Abdul Rahman, the modern founder of Saudi Arabia. The House of Saud ( Arabic: آل سُعُود, romanized: ʾĀl Suʿūd IPA: ) is the ruling royal family of Saudi Arabia.
