Vanadium(II) bromide is a inorganic compound with the formula VBr2. It adopts the cadmium iodide structure, featuring octahedral V(II) centers.{{cite journal |doi=10.1002/zaac.19422490204|title=Zur Kenntnis der Dihalogenide des Titans und Vanadins|year=1942|last1=Klemm|first1=Wilhelm|last2=Grimm|first2=Ludwig|journal=Zeitschrift für Anorganische und Allgemeine Chemie|volume=249|issue=2|pages=198–208}} A hexahydrate is also known. The hexahydrate undergoes partial dehydration to give the tetrahydrate. Both the hexa- and tetrahydrates are bluish in color.{{cite journal |doi=10.1002/zaac.19623150108|title=Darstellung von Vanadin(II)-Verbindungen aus wäßriger Lösung|year=1962|last1=Seifert|first1=Hans-Joachim|last2=Gerstenberg|first2=Burkhard|journal=Zeitschrift für Anorganische und Allgemeine Chemie|volume=315|issue=1–2|pages=56–63}} The compound is produced by the reduction of vanadium(III) bromide with hydrogen.
