The Army of Helvetia, or (), was a command of the French Revolutionary Army. It was formed on 8 March 1798 from the remnants of the first unit to be known as the Army of the Rhine. It was officially merged into the command structure of the Army of the Danube on 29 April 1799, although it continued to operate in the Swiss theater until 1801. The Army's initial campaigning in the old Swiss Confederation resulted in severe setbacks and defeats at Feldkirch, Lusiensteig, and Zurich.
