In the title compound, C26H23FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The thiourea group is close to being coplanar with the pyrazole N atoms [N—N—C—S torsion angle = 176.78 (15)°], which allows for an intramolecular N—H...N hydrogen bond; the connected triazole ring is nearly coplanar with this ring [N—C—C—N = −172.65 (19)°]. There is a significant twist between the pyrazole ring and attached fluorobenzene ring [N—C—C—C = −18.8 (3)°] and a greater twist between triazole and attached tolyl ring [dihedral angle = 58.25 (14)°]. In the crystal, supramolecular chains aligned along [40,10] are consolidated by π–π interactions between the triazole and phenyl rings [centroid–centroid distance = 3.7053 (13) Å].
