A repeal (O.F. rapel, modern rappel, from rapeler, rappeler, revoke, re and appeler, appeal) is the removal or reversal of a law. There are two basic types of repeal; a repeal with a re-enactment is used to replace the law with an updated, amended, or otherwise related law, or a repeal without replacement so as to abolish its provisions altogether.

Removal of secondary legislation is normally referred to as revocation rather than repeal in the United Kingdom and Ireland. Under the common law of England and Wales, the effect of repealing a statute was "to obliterate it completely from the records of Parliament as though it had never been passed." This, however, is now subject to savings provisions within the Interpretation Act 1978.

In parliamentary procedure, the motion to rescind, repeal, or annul is used to cancel or countermand an action or order previously adopted by the assembly.
