Zavaritskite is a rare mineral of the halide class, bismuth oxyhalide with the chemical formula (BiO)F.[1][2] It is named after the Soviet geologist and petrographer, academician of the USSR Academy of Sciences Alexander Nikolaevich Zavaritsky.

[3][4][5] Zavaritskite is a gray mineral with a greasy or semi-metallic luster; opaque, only slightly translucent in very small grains.

The crystallization process of zavaritskite occurs in a square system, due to which the mineral forms sufficiently fine-grained powder cryptocrystalline aggregates.

Also, the mineral was discovered in Russia at the Nevskoe tungsten-tin deposit near Omsukchan in the Magadan Oblast, at Pitkyaranta in the Republic of Karelia, and at Mount Ploskaya in the Keivy Mountains on the Kola Peninsula.

Other known sites to date are Fielders Hill near Torrington (Clive County) and the Elsmore tin mine in Inverell Shire (Gough County) in the Australian state of New South Wales; the Beauvoir quarry near Échassières in the French département of Allier; the Ebisu pits near Nakatsugawa and Ashio near Nikkō on the Japanese island of Honshu; and several others.
