Prince Andrew, Duke of York is a member of the British royal family. He is the third child and second son of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, and a younger brother of King Charles III. Andrew was born second in the line of succession to the British throne and is now eighth, and the first person in the line who is not a descendant of the reigning monarch.

Succession to the British throne is determined by descent, sex, legitimacy, and religion. Under common law, the Crown is inherited by a sovereign's children or by a childless sovereign's nearest collateral line. The Bill of Rights 1689 and the Act of Settlement 1701 restrict succession to the throne to the legitimate Protestant descendants of Sophia of Hanover who are in "communion with the Church of England". Spouses of Catholics were disqualified from 1689 until the law was amended in 2015. Protestant descendants of those excluded for being Roman Catholics are eligible.
