The title compound, C10H11I2NO, was prepared by the reaction of 3,5-diiodo­salicyl­aldehyde with propyl­amine in ethanol. The mol­ecule adopts an E conformation with respect to the C=N bond and the aromatic ring. The aromatic ring and the imino unit are close to being coplanar, with a dihedral angle of 2.6 (3)° between their planes. This planarity is assisted by the formation of an intra­molecular O—H⋯O hydrogen bond.
