Meyerhofferite is a hydrated borate mineral of calcium, with the chemical formula Ca₂B₆O₆(OH)₁₀·2H₂O,^[3] CaB₃O₃(OH)₅·H₂O^[4] or Ca₂(H₃B₃O₇)₂·4H₂O.^[5] It occurs principally as an alteration product of inyoite, another borate mineral.

Natural meyerhofferite was discovered in 1914 in Death Valley, California It is named for German chemist Wilhelm Meyerhoffer (1864–1906), collaborator with J. H. van't Hoff on the composition and origin of saline minerals, who first synthesized the compound.^[5]
