Dzhalindite is a rare indium hydroxide mineral discovered in Siberia. Its chemical formula is In(OH)₃.

It was first described in 1963 for an occurrence in the Dzhalinda tin deposit, Malyi Khingan Range, Khabarovskiy Kray, Far-Eastern Region, Russia.{{cite journal | last1 = Genkin | first1 = A.D. | last2= I.V. | first2 = Murav’eva | year =1963 | title = Indite and dzhalindite – new indium minerals | journal = Zap.

It has also been reported from Mount Pleasant, New Brunswick, Canada; the Flambeau mine, Ladysmith, Rusk County, Wisconsin, US; in the Mangabeira tin deposit, Goiás, Brazil; Attica, mines of the Lavrion District, Greece; the Ore Mountains in Germany and the Czech Republic; the Chūbu region, Honshu Island, Japan; and the Arashan Massif of Tashkent, Uzbekistan.
