A liquid processing method for liquid-processing a substrate includes setting a substrate on a substrate holding device which rotates the substrate such that the substrate is held in horizontal position, supplying processing liquid to center portion of the substrate such that the center portion positioned center side with respect to peripheral portion of the substrate is liquid-processed, positioning a discharge port of a processing liquid nozzle toward downstream side in rotation direction such that the liquid is discharged to the peripheral portion obliquely to surface of the substrate and along tangential direction of the substrate while the substrate is rotated, and discharging gas from a gas nozzle perpendicularly to the surface of the substrate toward position that is adjacent to liquid landing position of the liquid on the surface of the substrate and is on the center side of the substrate, while the liquid is discharged to the peripheral portion.
