Inesite is a hydrous calcium manganese silicate mineral.{{Cite book|title=The Audubon Society Field Guide to North American Rocks And Minerals|last=Chesterman|first=Charles|publisher=Knopf|year=1978|pages=592}}  Its chemical formula is Ca₂Mn₇Si₁₀O₂₈(OH)₂•5(H₂O). Inesite is an inosilicate with a triclinic crystal system. It has a Mohs hardness of 5.5 to 6, and a specific gravity of 3.0. Its name originates from the Greek Ίνες ({{lang|grc-Latn|ines}}), "fibers" in allusion to its color and habit.
