Army general is the highest ranked general officer in many countries that use the French Revolutionary System. Army general is normally the highest rank used in peacetime.

In countries that adopt the general officer four-rank system, it is the rank of a general commanding a field army. However, in some countries such as Brazil, Ecuador and Peru, which have adopted the three-rank system, the rank of army general is immediately above that of divisional general. As such, it is the rank of commander of an army corps or larger formations. The equivalent position in the Commonwealth, U.S., and several other countries is simply general, four-star rank, or informally "full general".

The title "army general" should not be confused with the rank "general of the army", which is more senior, and corresponds to marshal or field marshal.
