Colemanit, mit der chemischen Formel Ca2B6O11·5H2O oder alternativ CaB3O4(OH)3·H2O, ist ein Boratmineral, das typischerweise in Evaporit-Lagerstätten in alkalischen Seeumgebungen vorkommt. Dieses sekundäre Mineral entsteht durch die Umwandlung von Borax und Ulexit. Es wurde erstmals 1884 in der Nähe von Furnace Creek im Death Valley identifiziert und nach William Tell Coleman benannt, dem Inhaber der Harmony Borax Works, wo es entdeckt wurde. Interessanterweise schlug Coleman ursprünglich den Namen „Smithit“ vor, um seinen Geschäftspartner Francis Marion Smith zu ehren.
