The whole mol­ecule of the title coumarin derivative, C11H10O3, is approximately planar, with a maximum deviation of 0.116 (3) Å from the least-squares plane defined by all non-H atoms. In the crystal, adjacent mol­ecules are linked into chains along [011] via inter­molecular C—H(...)O hydrogen bonds.
