The 4th Infantry Division "Livorno" (Italian: 4ª Divisione di fanteria "Livorno") was a infantry division of the Royal Italian Army during World War II. The Livorno was classified as a mountain infantry division, which meant that the division's artillery was moved by pack mules instead of the horse-drawn carriages of line infantry divisions. Italy's real mountain warfare divisions were the six alpine divisions manned by Alpini mountain troops. The Livorno was formed on 5 April 1939 in Cuneo and named for the city of Livorno.
