'''Tamarugite''' (NaAl(SO<sub>4</sub>)<sub>2</sub>·6H<sub>2</sub>O) is a colorless monoclinic sulfate mineral.<ref name=WebMineral>[http://webmineral.com/data/Tamarugite.shtml Webmineral.com - Tamarugite]</ref><ref name=Mindat>[http://www.mindat.org/min-3878.html Mindat.org - Tamarugite]</ref>

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