Curium hydroxide Cm(OH)₃ is a radioactive compound first discovered in measurable quantities in 1947. It is composed of a single curium atom and three hydroxy groups. It was the first curium compound ever isolated.^[3]^[4]

Curium hydroxide is an anhydrous colorless^[2] or light-yellow^[5] amorphous gelatinous solid that is insoluble in water.^[1]

Due to self-irradiation, the crystal structure of ²⁴⁴Cm(OH)₃ decomposes^{[clarification needed]} within one day (²⁴⁴Cm has a half-life of 18.11 years); for ²⁴¹Am(OH)₃ the same process takes 4 to 6 months (²⁴¹Am has a half-life of 432.2 years).^[2]
