Moschellandsbergite is a rare isometric mineral made up of a silver-white amalgam of mercury and silver with the chemical makeup Ag₂Hg₃.

It was first described in 1938 and named after Moschellandsberg Mountain near Obermoschel, Rhineland-Palatinate, Germany.{{Cite book | author= American Geological Institute | title = Dictionary of Mining, Mineral, and Related Terms | publisher = Birkhäuser | location = Alexandria, Virginia | pages = 356 | year = 1997 | isbn = 0-922152-36-5}} It is considered a low-temperature hydrothermal mineral which occurs with metacinnabar, cinnabar, mercurian silver, tetrahedrite–tennantite, pyrite, sphalerite and chalcopyrite.
