The asymmetric unit of the title compound, (C 6 H 9 N 2 ) 4 [V 4 O 12 ]·4H 2 O, contains half of a [V 4 O 12 ] 4−  anion, two 2-amino-4-methyl­pyridinium, (2a4mpH) + , cations and two water mol­ecules. One water mol­ecule is disordered over two sets of sites with equal occupancies and the H atoms for this mol­ecule were not included in the refinement. The cation lies on an inversion center with four tetra­hedral VO 4  units each sharing two vertices, forming an eight-membered ring. In the crystal, the components are linked by inter­molecular N—H⋯O hydrogen bonds, forming a one-dimensional network along [100]. Further stabilization is provided by weak inter­molecular C—H⋯O hydrogen bonds. In addition, π–π stacking inter­actions with centroid–centroid distances of 3.5420 (18), 3.7577 (18) and 3.6311 (19) Å are observed.
