Meneghinite is a sulfosalt mineral with the chemical formula CuPb13 Sb7S24.[4]

In the orthorhombic crystal system, meneghinite has a Mohs hardness of 2+1⁄2, one perfect cleavage and a conchoidal fracture. It is a blackish lead-grey in colour and gives a black shining streak. Its lustre is metallic.[4]

Discovered in the Italian Province of Lucca in 1852,[4] it is named after Giuseppe Meneghini (1811–1889) of the University of Pisa, who first observed the species.[5] The Bottino Mine in Lucca is the type locality.[4]
