Sodium tetrafluoroborate is an inorganic compound with formula NaBF₄. It is a salt that forms colorless or white rhombic crystals and is soluble in water (108 g/100 mL) but less soluble in organic solvents.^[1]

Sodium tetrafluoroborate is used in some fluxes used for brazing and to produce boron trifluoride.^[2]
