Scandium acetate is a compound, with the chemical formula of Sc(CH₃COO)₃. It exists in the anhydrous and the hydrate forms. It can be obtained by reacting scandium hydroxide or scandium oxide with acetic acid. ^{[1] [2]} It is a colorless, water-soluble solid. It decomposes into scandium oxide at high temperature. It can be used to prepare other scandium-containing materials. ^[3]

The structure of the anhydrous form was determined by X-ray crystallography. It consists of a chain of octahedral Sc(III) centers linked by bridging acetate ligands. ^[1]
