Kalgoorlieite (IMA2015-119) is a mineral from Kalgoorlie, Western Australia.

Kalgoorlieite is the fourth oxygen-free arsenic-tellurium mineral after benleonardite, debattistiite, and törnroosite.{{fact|date=July 2022}}

It was discovered in 2015 by a Curtin University academic Dr Kirsten Rempel while she was checking samples in the Kalgoorlie School of Mines Museum, and declared a new mineral in 2016, after verification and classification.Rempel, K., Stanley, C.J.
