A stable liquid composition comprising a botulinum toxin as an active ingredient is described, which is ready-to-use without the need for a reconstitution process, and thus, it is possible to improve user's convenience, and reduce a deviation of botulinum toxin activity due to dilution errors in the reconstitution process. Further, the liquid composition efficiently prevents the botulinum toxin from aggregating even at a low botulinum toxin concentration to thereby have extremely excellent storage stability, and efficiently prevents adsorption of the botulinum toxin to a container, thereby constantly maintaining an activity of the botulinum toxin for each batch or for each liquid vial.
