In the title compound, C9H6FNO2, all the non-H atoms are approximately coplanar, the carboxy O atoms deviating by 0.0809 and −0.1279 Å from the indole plane. In the crystal, O—H⋯O hydrogen bonds link the molecules into dimers which are linked via N—H⋯O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.680 (2) Å]
