In the title compound, C20H14BrN3O3S, the mol­ecule adopts an E configuration about the central C=N double bond. The chromene ring system and the thia­zole ring are approximately planar [maximum deviations = 0.029 (3) and 0.007 (3) Å, respectively]. The chromene ring system is inclined at angles of 7.37 (12) and 13.90 (13)° with respect to the thia­zole and benzene rings, respectively, while the thia­zole ring makes a dihedral angle of 12.58 (15)° with the benzene ring. In the crystal, mol­ecules are connected by N—H⋯O hydrogen bonds, forming C(8) supra­molecular chains along the c axis.
