The Deputy President of the Supreme Court of the United Kingdom is the second most senior judge of the Supreme Court of the United Kingdom, after the President of the Supreme Court. The office is equivalent to the now-defunct position of Second Senior Lord of Appeal in Ordinary, also known previously as the Second Senior Law Lord, who was the second highest-ranking Lord of Appeal in Ordinary.

The Supreme Court of the United Kingdom is the final court of appeal in the United Kingdom for all civil cases, and for criminal cases originating in England, Wales and Northern Ireland. As the United Kingdom’s highest appellate court for these matters, it hears cases of the greatest public or constitutional importance affecting the whole population.
