Phthalocyanine (H₂Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C₈H₄N₂)₄H₂ and is of theoretical or specialized interest in chemical dyes and photoelectricity.

It is composed of four isoindole units^[a] linked by a ring of nitrogen atoms. (C₈H₄N₂)₄H₂ = H₂Pc has a two-dimensional geometry and a ring system consisting of 18 π-electrons. The extensive delocalization of the π-electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. Metal complexes derived from Pc²⁻
, the conjugate base of H₂Pc, are valuable in catalysis, organic solar cells, and photodynamic therapy.
