Stolzite is a mineral, a lead tungstate; with the formula PbWO₄. It is similar to, and often associated with, wulfenite which is the same chemical formula except that the tungsten is replaced by molybdenum. Stolzite crystallizes in the tetragonal crystal system and is dimorphous with the monoclinic form raspite.

Lead tungstate crystals have the optical transparency of glass combined with much higher density (8.28 g/cm³ vs ~2.2 g/cm³ for fused silica). They are used as scintillators.

It was first described in 1845 for an occurrence in Krusne Hory (Erzgebirge), Czech Republic and named after Joseph Alexi Stolz of Teplice in Bohemia. It occurs in oxidized hydrothermal tungsten-lead ore deposits typically in association with raspite, cerussite, anglesite, pyromorphite and mimetite.
