The Museums and Galleries Act 1992 (c. 44) is an act of the Parliament of the United Kingdom.
This act legislates the operation and financing of the museums mentioned in its title. For example, it establishes that the National Portrait Gallery is to "maintain a collection of portraits in all media of the most eminent persons in British history from the earliest times to the present day".
The act provides the prime minister's power to appoint the members of the Boards of Trustees of the National Gallery (except one member), the Tate Gallery (except one member), the National Portrait Gallery, and the Wallace Collection.
The act repealed the National Gallery and Tate Gallery Act 1954.
According to the National Gallery, the act prevents it from disposing of items, unless it is to other recognised national bodies.
