The 12th Heavy Field Artillery Regiment (Italian: 12° Reggimento Artiglieria Pesante Campale) is an inactive artillery regiment of the Italian Army, which was based in Vercelli in Piedmont and assigned to the 3rd Army Corps.

During World War II the regiment formed an army corps artillery grouping, which in 1943 fought against the allies during the invasion of Sicily.

The regiment and its depot were lost when allied forces entered Palermo on 22 July 1943, while the grouping was disbanded in August 1943 after it had retreated from Sicily to Calabria in Southern Italy.

In 1986 the division was disbanded, the group was transferred to the Artillery Command of the 3rd Army Corps.

The group was named for the city of Biella, which had been one of the centers of the Italian resistance movement during the German occupation of Italy in World War II.

On 13 July 1987 the President of the Italian Republic Francesco Cossiga confirmed the assignment of the flag of the 12th Heavy Field Artillery Regiment to the group.
