Vanadiocarpholite (Mn<sup>2+</sup>V<sup>3+</sup>AlSi<sub>2</sub>O<sub>6</sub>(OH)<sub>4</sub>) is straw yellow to brown silicate mineral. It crystallizes in the orthorhombic crystal system. It is the vanadium rich variety of carpholite (Mn<sup>2+</sup>Al<sub>2</sub>Si<sub>2</sub>O<sub>6</sub>(OH)<sub>4</sub>).
It was first described in 2005 for an occurrence in the Molinello Mine, Graveglia Valley, Genova Province, Liguria, Italy. It occurs in chert in a manganese ore deposit as vein fillings in silicified wood.
