The 2nd Anti-aircraft Artillery Regiment (Italian: 2° Reggimento Artiglieria Controaerei) is an inactive air defence regiment of the Italian Army, which was based in Ravenna in the Emilia-Romagna. Originally an air defence regiment of the Royal Italian Army, the unit was last active from 1992 to 1996.^[1] The regimental anniversary falls, as for all Italian Army artillery regiments, on June 15, the beginning of the Second Battle of the Piave River in 1918.^[1]

On 30 October 1926 the 10th Anti-aircraft Artillery Center was formed in Naples, which incorporated the existing 8th Anti-aircraft Group. On 1 January 1927 the center consisted of a command, a mixed group with two training batteries equipped with 75/27 C.K. anti-aircraft guns and one training battery equipped with 76/45 anti-aircraft guns, a photo-electricians unit, and a depot. The center's photo-electricians operated searchlights.^[1]

On 1 April 1930 the center received from the 5th Anti-aircraft Artillery Center a trucked group with 75/27 C.K. anti-aircraft guns and a photo-electricians unit. On 1 June of the same year the center changed its name to 2nd Trucked Anti-aircraft Artillery Regiment. In April 1931 the two photo-electricians units were disbanded and in each of the two groups a photo-electricians section and a acoustic locator squad were formed. In June of the same year the regiment received a trucked group with 75/27 C.K. anti-aircraft guns in Palermo from the disbanded 12th Anti-aircraft Artillery Center.^[1]

The two batteries and the regiment's II Trucked Group, which was redesignated VII Trucked Group, were deployed to Cyrenaica in Italian Libya. The regiment was demobilized on 9 July 1936, with the exception of the VII Trucked Group, which was based in Tobruk since 16 April 1936 and returned to Italy on 7 October, where the group was disbanded.^[1]
