Lithium permanganate is an inorganic compound with the chemical formula LiMnO4.

It can be produced by the reaction of lithium sulfate and barium permanganate, and the trihydrate LiMnO4·3H2O can be crystallized from the solution.

It decomposes violently at 199 °C:[2] However, later research found that the thermal decomposition products of lithium permanganate are more complex, with products such as Li2MnO3 and LiMn2O4 being generated.
