The Army of Mainz or Army of Mayence was a French Revolutionary Army set up on 9 December 1797 by splitting the Army of Germany into the Army of Mayence and the Army of the Rhine. Part of it split off on 4 February 1799 to form the Army of Observation, though part of that army then re-merged as the Army of Mayence on 28 March that year. The remainder formed the Army of the Danube.
