The 5th Heavy Field Artillery Regiment (Italian: 5° Reggimento Artiglieria Pesante Campale) is an inactive artillery regiment of the Italian Army, which was based in Udine in Friuli-Venezia Giulia and assigned to the 5th Army Corps.

During World War II the regiment formed two army corps artillery groupings, one of which participated in 1941 in the invasion of Yugoslavia and then remained there on occupation duty.

The other grouping was sent in December 1942 to North Africa, where it participated in the Tunisian campaign and surrendered to allied troops in May 1943.

The regiment and its remaining grouping were disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.

On 13 July 1987 the President of the Italian Republic Francesco Cossiga confirmed the assignment of the flag of the 5th Heavy Field Artillery Regiment to the group.
