In the title compound, C20H14FN3O, the quinoxaline system makes dihedral angles of 32.38 (7) and 48.04 (7)° with the 4-fluorophenyl and pyridine rings, respectively. The 4-fluorophenyl ring makes a dihedral angle of 57.77 (9)° with the pyridine ring. In the crystal, the molecules form dimeric C—H...N hydrogen-bonded R22(20) ring motifs lying about crystallographic inversion centers. The dimeric units stack via π–π interactions between methoxyphenyl rings and pyridine–fluorophenyl rings with centroid–centroid distances of 3.720 (1) and 3.823 (1) Å, respectively. The respective average perpendicular distances are 3.421 and 3.378 Å, with dihedral angles between the rings of 1.31 (9) and 11.64 (9)°.
