Nekrasovite is a rare copper vanadium sulfosalt mineral with formula {{chem2|Cu26V2(Sn,As,Sb)6S32}}. It crystallizes in the isometric system and occurs as small grains in ore aggregates. It is a brown opaque metallic mineral with Mohs hardness of 4.5 and a specific gravity of 4.62.

It was first described in 1984 in the Kayragach (Qayragʻoch) Au-Te ore deposit,[https://www.mindat.org/loc-2813.html Kairagach Au deposit, Ohangaron District, Tashkent Region, Uzbekistan] Ohangaron District, Tashkent Region, eastern Uzbekistan and named for Russian mineralogist {{ill|Ivan Yakovlevich Nekrasov|ru|Некрасов, Иван Яковлевич}}.
