The 6th Mountain Artillery Regiment (Italian: 6° Reggimento Artiglieria da Montagna) is an inactive mountain artillery regiment of the Italian Army, which was based in Bassano del Grappa in Veneto.

During World War II the regiment served in 1942 as occupation force in Montenegro and in 1943 in Liguria as coastal defence unit.

After the announcement of the Armistice of Cassibile on 8 September 1943 the regiment was disbanded two days later by invading German forces.

The Group "Val d'Adige" had been formed by the depot of the 2nd Alpine Artillery Regiment "Tridentina".

All of the regiment's batteries had already been active during World War I and served during that conflict on the Italian front.

On 9 December 1941 the Group "Val d'Adige" was transferred to Montenegro, where it was tasked with occupation and anti-partisan duties.

On 27 February 1942 the regiment's command was transferred to Montenegro, where it incorporated the Group "Val d'Adige" and received the Alpine Artillery Group "Valle Isonzo" from the 3rd Alpine Artillery Regiment "Julia".

The regiment moved to Acqui and was tasked with coastal defense duties in Liguria.

After the announcement of the Armistice of Cassibile on 8 September 1943 the regiment and its groups participated in the defense of the harbour of La Spezia, to allow the Royal Italian Navy ships to escape invading German forces.

Already on 25 September of the same year the Group "Lanzo" was reformed by the depot of the 5th Alpine Artillery Regiment "Pusteria" and now consisted of the 16th and 21st batteries.

[2][3][4] The Mountain Artillery Group "Agordo", named for the village of Agordo in the Cadore region, was formed for the first time in 1953 with the batteries, that had formed the Group "Val Tagliamento" in World War II.

In February 1963 the Group "Pieve di Cadore" moved from Strigno to Bassano del Grappa.

[2][3] In October 1963 the regiment was called up help mount the rescue operation and cleanup after the Vajont dam disaster.

The same day the Mountain Artillery Group "Agordo" in Bassano del Grappa and the Mountain Artillery Group "Lanzo" in Belluno became autonomous units and were assigned to the Alpine Brigade "Cadore".

[2][6] After the end of the Cold War the Italian Army began to draw down its forces.
