Thulium(III) hydroxide is an inorganic compound with the chemical formula Tm(OH)₃.

Chemical properties

Thulium(III) hydroxide reacts with acids and produces thulium(III) salts:

Tm(OH)₃ + 3 H⁺ → Tm³⁺ + 3 H₂O

Thulium(III) hydroxide decomposes to TmO(OH) at elevated temperature. Further decomposition produces Tm₂O₃.^[1]
