The Supreme Court of Civil Judicature of New South Wales was a court established in the early 19th century in the colony of New South Wales. The colony was subsequently to become a state of Australia in 1901. The court had jurisdiction to deal with civil disputes where the amount in dispute in the colony was more than £50 sterling. The Supreme Court of New South Wales replaced the court in 1823 when the Supreme Court was created by the Third Charter of Justice.

The Supreme Court of New South Wales is the highest state court of the Australian State of New South Wales. It has unlimited jurisdiction within the state in civil matters, and hears the most serious criminal matters. Whilst the Supreme Court is the highest New South Wales court in the Australian court hierarchy, an appeal by special leave can be made to the High Court of Australia.
