The British Museum Act 1816 or the Elgin Marbles Act (56 Geo. 3. c. 99) was an Act of the Parliament of the United Kingdom. The act authorised the Treasury to provide £35,000 to buy the Elgin Marbles for the British Museum, and enacted two other conditions imposed by Lord Elgin: that he and his successors would be appointed as trustees of the British Museum, and that the collection would be kept together and named 'The Elgin Collection'. The whole act was repealed by section 13(5) of, and schedule 4 to, the British Museum Act 1963.
