List of Acts of Parliament of the United Kingdom Parliament, 1900–1999

This is an "incomplete" list of Acts of the Parliament of the United Kingdom for the years 1900-1999. For acts passed prior to 1707 see List of Acts of Parliament of the English Parliament and List of Acts of the Scottish Parliament to 1707.

For Acts of the Scottish Parliament passed since the establishment of the modern version in 1999 also see the list of Acts of Parliament of the Scottish Parliament. For Acts of the Northern Ireland Assembly see List of Acts of the Northern Ireland Assembly and for Acts of the Northern Ireland Parliament see List of Acts of the Northern Ireland Parliament.

The numbers after the titles of the acts are the chapter numbers. Before 1962, acts were generally referenced using 'Year of reign', 'Monarch', c., 'Chapter number' — e.g. 16 Charles II c. 2 — to define a chapter of the appropriate statute book. Since 1962, the regnal year has been replaced by the calendar year, including in references to Acts before 1962. All recent Acts have a short title, or citation (e.g. Local Government Act 2003, National Health Service Act 1974). After 1948, Private Acts were renamed Personal Acts.
