The Incitement to Mutiny Act 1797 (37 Geo. 3. c. 70) was an act of the Parliament of Great Britain. The act was passed in the aftermath of the Spithead and Nore mutinies and aimed to prevent the seduction of sailors and soldiers to commit mutiny.

The act was revived and made perpetual by the Allegiance of Sea and Land Forces Act 1817 (57 Geo. 3. c. 7).

The Parliament of Ireland passed an equivalent act in the same year: the Incitement to Disaffection Act (Ireland) 1797 (37 Geo. 3. c. 40 (I)).

Section 1 of the act provided:

Any person who shall maliciously and advisedly endeavour to seduce any person or persons serving in His Majesty's forces, by sea or land, from his or their duty and allegiance to His Majesty, or incite or stir up any such person or persons to commit any act of mutiny, or to make, or endeavour to make, any mutinous assembly, or to commit any traitorous or mutinous practice whatsoever, shall on being legally convicted of such offence, be adjudged guilty of felony ...

The words at the end were repealed by the Statute Law Revision Act 1888 (51 & 52 Vict. c. 3).

The reference to felony was construed as a reference to "an offence" following the Criminal Law Act 1967 and the Criminal Law Act (Northern Ireland) 1967.

The offence was extended to members of the Royal Air Force by the Air Force (Application of Enactments) (No 2) Order 1918 (S.R. & O. 1918/548).
