Nitronium tetrafluoroborate is an inorganic compound with formula NO₂BF₄. It is a salt of nitronium cation and tetrafluoroborate anion.{{Cite journal |last=Krossing |first=Ingo |last2=Raabe |first2=Ines |last3=Birtalan |first3=Esther |date=2007-01-12 |title=Nitronium tetrafluoroborate |url=https://scripts.iucr.org/cgi-bin/paper?S1600536807000207 |journal=Acta Crystallographica Section E: Structure Reports Online |volume=63 |issue=2 |pages=i43–i44 |doi=10.1107/S1600536807000207 |issn=1600-5368}} It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO₃. As such, it must be handled under water-free conditions. It is sparsely soluble in many organic solvents.
