The Supreme Court of Pakistan is the apex court in the judicial hierarchy of the Islamic Republic of Pakistan.

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.
