The Supreme Court of Judicature Act (Ireland) 1877 was an Act of the Parliament of the United Kingdom that brought about a major reorganisation of the superior courts in Ireland. It created a Supreme Court of Judicature, comprising the High Court of Justice in Ireland and the Court of Appeal in Ireland. It mirrored in Ireland the changes which the Supreme Court of Judicature Act 1873 had made in the courts of England and Wales.
