Routhierite is a rare thallium sulfosalt mineral with formula Tl(Cu,Ag)(Hg,Zn)2(As,Sb)2S6.
It was first described in 1974 for an occurrence in the Jas Roux deposit in the French Alps. It was named after French geologist Pierre Routhier (1916–2008). It is also reported from the Northern Ural Mountains, Russia and the Thunder Bay district of Ontario, Canada.
