Indium acetate is an acetate of indium, with the chemical formula In(CH3COO)3.

It is soluble in water, acetic acid and mineral acids.

[1] It is the precursor of indium-containing compounds such as the solar cell materials CuInS2[2] and indium phosphide quantum dots.

[3] Indium acetate can be prepared by reacting indium[4] or triethylindium[5] with frozen acetic acid.

Indium acetate can react with propionic acid:[4]
