The tetra­nuclear title complex, [Cu 4 (C 7 H 4 O 3 ) 2 (OH) 2 (C 10 H 8 N 2 ) 4 ](NO 3 ) 2 ·4H 2 O, has a crystallographically imposed centre of symmetry. The Cu II  atoms display a distorted square-pyramidal coordination geometry and are linked by two μ 2 -phenolate O atoms from the salicylate ligands and two μ 3 -hydroxo groups, forming a Cu 4 O 4  core that adopts a ‘stepped-cubane’ geometry. In the crystal, the cations are linked by O—H⋯O hydrogen bonds to the nitrate anions, which are in turn connected  via  O—H⋯O inter­actions to centrosymmentric water tetra­mers.
