The title mol­ecule, C17H11FN2O3, is nearly planar [maximum deviation = 0.197 (1) Å] and the mol­ecular conformation is stabilized by an N—H...O hydrogen bond forming an S(6) ring motif. The H atom of the intra­molecular hydrogen bond was found to be disordered over two sites and thus both the hy­droxy and keto tautomers are simultaneously present in the solid. Refinement of the occupancy of this site suggests that the hy­droxy form is the major component [occupancy refined to 0.59 (3):0.41 (3)]. Bond lengths are also largely consistent with dominance of the hy­droxy form. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds, forming layers parallel to (101). π–π stacking inter­actions [centroid–centroid distances = 3.5649 (9) and 3.7579 (9) Å] inter-connect these layers.
