The 151st Infantry Division "Perugia" was an infantry division of the Royal Italian Army during World War II. The Perugia was formed on 25 August 1941 and named for the city of Perugia. The Perugia was classified as an occupation infantry division, which meant that the division's artillery regiment consisted of two artillery groups instead of the three artillery groups of line infantry divisions and that the divisional mortar battalion was replaced by a divisional machine gun battalion.
