Kukharenkoite-(Ce) is a barium cerium fluoride carbonate mineral, formula Ba2CeF(CO3)3. It was identified from samples found in the Mont-Saint-Hilaire alkaline intrusive complex, Quebec, and the Khibiny Massif, Kola Peninsula, Russia. It was named for Russian mineralogist Alexander A. Kukharenko (1914–1993).
- Category: Carbonate minerals
- Formula: Ba2CeF(CO3)3
- Crystal system: Monoclinic
- Crystal class: Prismatic (2/m) (same H-M symbol)
- Type Locality: Khibina and Vuorijärvi massifs, Russia; Mt St-Hilaire and St-Amable, Canada.
The similar zhonghuacerite, a cerium-containing mineral from China, is considered to be either Kukharenkoite-(Ce) or huanghoite-(Ce) rather than a valid mineral.
