The 109th (Aberdeenshire) Regiment of Foot was an infantry regiment of the British Army from 1794 to 1795. Raised by Alexander Leith Hay for service in the French Revolutionary Wars the regiment was briefly deployed in Jersey before it was disbanded in England and its men sent to reinforce the 53rd (Shropshire) Regiment of Foot. The disbandment was controversial as Leith-Hay believed it contravened an assurance given to him in his original letter of service to raise the regiment.
