The Hong Kong Court of Final Appeal is the final appellate court of Hong Kong. It was established on 1 July 1997, upon the establishment of the Hong Kong Special Administrative Region, replacing the Judicial Committee of the Privy Council as the highest judicial institution under Hong Kong law. As defined in Articles 19 and 85 of the Basic Law of Hong Kong, the Court of Final Appeal "exercises judicial power in the Region independently and free from any interference." The Hong Kong Court of Final Appeal Ordinance and the Hong Kong Court of Final Appeal Rules set out the detailed functions and procedures of the court.

In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and high court of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A Supreme Court can also, in certain circumstances, act as a court of original jurisdiction, however, this is typically limited to constitutional law.
