The Statute Law Revision Act 1891 (54 & 55 Vict. c. 67) is an act of the Parliament of the United Kingdom that repealed various United Kingdom enactments which had ceased to be in force or had become unnecessary. The act was intended, in particular, to facilitate the preparation of the new edition of the revised edition of the statutes, then in progress.

In the United Kingdom, acts of Parliament remain in force until expressly repealed. Blackstone's Commentaries on the Laws of England, published in the late 18th-century, raised questions about the system and structure of the common law and the poor drafting and disorder of the existing statute book.

In 1806, the Commission on Public Records passed a resolution requesting the production of a report on the best mode of reducing the volume of the statute book. From 1810 to 1825, The Statutes of the Realm was published, providing for the first time the authoritative collection of acts. In 1816, both Houses of Parliament, passed resolutions that an eminent lawyer with 20 clerks be commissioned to make a digest of the statutes, which was declared "very expedient to be done." However, this was never done.

At the start of the parliamentary session in 1853, Lord Cranworth announced his intention to the improvement of the statute law and in March 1853, appointed the Board for the Revision of the Statute Law to repeal expired statutes and continue consolidation, with a wider remit that included civil law. The Board issued three reports, recommending the creation of a permanent body for statute law reform.

In 1854, Lord Cranworth appointed the Royal Commission for Consolidating the Statute Law to consolidate existing s and enactments of English law. The Commission made four reports.

An alternative approach, focusing on expunging obsolete laws from the statute book, followed by consolidation, was proposed by Peter Locke King MP, who was heavily critical of the expenditure of the Commission and the lack of results. This approach was taken by the Repeal of Obsolete Statutes Act 1856 (19 & 20 Vict. c. 64), considered to be the first Statute Law Revision Act.

On 17 February 1860, the Attorney General, Sir Richard Bethell told the House of Commons that he had engaged Sir Francis Reilly and A. J. Wood to expurgate the statute book of all acts which, though not expressly repealed, were not in force, working backwards from the present time.

The Statute Law Revision Bill had its first reading in the House of Lords on 19 March 1891, introduced by the Lord Chancellor, Hardinge Giffard, 1st Earl of Halsbury. The bill had its second reading in the House of Lords on 4 May 1891 and was committed to a committee of the whole house, which met and reported on 8 May 1891, without amendments. The bill had its third reading in the House of Lords on 11 May 1891 and passed, with amendments.
