Gallium hydroxide is an inorganic compound with the chemical formula {{chem2|Ga(OH)3|auto=1}}. It is formed as a gel following the addition of ammonia to {{chem2|Ga(3+)}} salts.Anthony John Downs, (1993), Chemistry of Aluminium, Gallium, Indium, and Thallium, Springer, {{ISBN|978-0-7514-0103-5}} It is also found in nature as the rare mineral söhngeite which is reported to contain octahedrally coordinated gallium atoms. Crystal Structure of a new mineral söhngeite, J.D. Scott, The American Mineralogist, (1971), 56, 355

Gallium hydroxide is amphoteric. In strongly acidic conditions, the gallium ion, {{chem2|Ga(3+)}} is formed. In strongly basic conditions, {{chem2|[Ga(OH)4]−}} (tetrahydroxogallate(III)) is formed. Salts of {{chem2|[Ga(OH)4]−}} are sometimes called gallates.
