Tamarugite (NaAl(SO4)2·6H2O) is a colorless monoclinic sulfate mineral.[2][3]

Deposits containing tamarugite are geographically dispersed with occurrences of the mineral on all seven continents (Antarctica, Oceania, North America, South America, Europe, Asia, Africa).[3] The mineral's name comes from the Tamarugal Pampa locality in Chile.[2][3] It is also known as lapparentite.
