Aktashite is a rare arsenic sulfosalt mineral with formula Cu₆Hg₃As₄S₁₂. It is a copper mercury-bearing sulfosalt and is the only sulfosalt mineral with essential Cu and Hg yet known. It is of hydrothermal origin. It was published without approval of the IMA-CNMNC, but recognized as valid species by the IMA-CNMNC Sulfosalts Subcommittee (2008).^{[2][3][4][5][6]}
