The Supreme Court of Judicature at Fort William in Calcutta, was founded in 1774 by the Regulating Act of 1773. It replaced the Mayor's Court of Calcutta and was British India's highest court from 1774 until 1862, when the High Court of Calcutta was established by the Indian High Courts Act 1861.

The Calcutta High Court is the oldest High Court in India. It is located at Esplanade Row West, Kolkata, West Bengal. It has jurisdiction over the state of West Bengal and the Union Territory of the Andaman and Nicobar Islands. The High Court building's design is somewhat based on the Lakenhal in Ypres in Flanders, Belgium.
