In the title compound, [Cu(SO4)(C15H11N5)(H2O)]·CH3OH·2H2O, the CuII ion is in a distorted square-pyramidal geometry, in which three N atoms from the chelating 1-(1,10-phenanthrolin-2-yl)-1H-pyrazol-3-amine ligand and one O atom from a sulfate anion define the basal plane and the O atom from the coordinating water mol­ecule is located at the apex. In the crystal, hydrogen-bonding inter­actions involving the coordinating and solvent water mol­ecules, the methanol solvent mol­ecule and the amine group (one with an intra­molecular inter­action to one of the sulfate O atoms) of the complex are observed. π–π inter­actions between symmetry-related phenantroline moieties, with a shortest centroid–centroid inter­action of 3.573 (2)°, are also present.
