Thulium(III) oxalate is the oxalate of thulium with the chemical formula Tm₂(C₂O₄)₃. Its hydrate can be prepared by reacting an aqueous solution of thulium(III) chloride and a benzene solution of dimethyl oxalate. Its pentahydrate is decomposed by heat to obtain the dihydrate, which is further heated to obtain thulium(III) oxide. It reacts with hydrochloric acid to obtain H[Tm(C₂O₄)₂]·6H₂O.
