- Named in honour of Franz Xavier Wulfen (1728–1805), Austrian–German Jesuit, who wrote a monograph on the lead ores of Bleiberg, Austria.
- Wulfenite was voted “Mineral of the Year” in Austria in 2020.
- In its pure form wulfenite is colorless; the often yellow to red colour is most probably due to trace amounts of chromium substituting Mo.
- Formula: PbMoO4
- Space group: I41/a (No. 88)
- Crystal system: tetragonal
- Crystal class: 4/m
- Lattice parameters: a = b = 5.434 Å, c = 12.107 Å, α = β = γ = 90°
