'''Jordanite''' is a sulfosalt mineral with chemical formula {{chem2|Pb14(As,Sb)6S23}} in the monoclinic crystal system,<ref name=mindat>[http://www.mindat.org/min-2113.html Mindat information page for Jordanite]</ref> named after the German scientist H. Jordan (1808–1887) who discovered it in 1864.
Lead-grey in colour (frequently displaying an iridescent tarnish), its streak is black and its lustre is metallic. Jordanite has a hardness of 3 on Mohs scale, has a density of approximately 6.4, and a conchoidal fracture.<ref name=mindat />
The type locality is the Lengenbach Quarry in the Binn Valley, Wallis, Switzerland.<ref name=mindat />
