Cobalt(II) Nitrate Hexahydrate is an inorganic cobalt salt with the chemical formula Co(NO₃)₂·6H₂O. It is the most common hydrated form of cobalt nitrate and appears as a red to red-brown, hygroscopic crystalline solid that is readily soluble in water and other polar solvents. The compound is also known as hexaaquacobalt(II) nitrate because it consists of [Co(H₂O)₆]²⁺ cations and nitrate (NO₃⁻) anions. Because of its high solubility and stability under normal conditions, it serves as an important cobalt precursor in chemical synthesis, materials science and laboratory research.

Cobalt(II) Nitrate Hexahydrate is used in the synthesis of cobalt oxide nanomaterials, preparation of catalysts, battery materials, electrocatalysts, coordination compounds and scientific research.
Cobalt(II) nitrate hexahydrate is very soluble in water and other polar solvents, which makes it useful in laboratory and industrial applications.
Cobalt(II) Nitrate Hexahydrate is usually produced by reacting cobalt metal, cobalt oxide or cobalt carbonate with nitric acid and crystallization to obtain the hexahydrate.
Cobalt(II) Nitrate Hexahydrate is hygroscopic, which means it easily absorbs moisture from the air and should be stored in tightly sealed containers in dry conditions.
