The 33rd Infantry Division "Acqui" (Italian: 33ª Divisione di fanteria "Acqui") was an infantry division of the Royal Italian Army during World War II. The Acqui was classified as a mountain infantry division, which meant that its 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 division was named for the city of Acqui. The division is notable for having been massacred with remarkable cruelty after surrendering to the Germans on 21 September 1943. The main detachments of the Acqui division in the islands of Cephalonia and Corfu were officially dissolved 25 September 1943.
