In the mol­ecule of 3-chloro-2-(4-methyl­phen­yl)-2H-pyrazolo­[3,4-b]quinoline, C17H12ClN3, (I), the dihedral angle between the planes of the pyrazole ring and the methyl­ated phenyl ring is 54.25 (9)°. The bond distances in the fused tricyclic system provide evidence for 10-π delocalization in the pyrazolo­pyridine portion of the mol­ecule, with diene character in the fused carbocyclic ring. In the crystal, mol­ecules of (I) are linked by two independent C—H⋯N hydrogen bonds, forming sheets containing centrosymmetric R22(16) and R64(28) rings, and these sheets are all linked together by π–π stacking inter­actions with a ring-centroid separation of 3.5891 (9) Å.
