An object of the present invention is to provide a water-developable flexographic printing plate precursor, a flexographic printing plate, and a photosensitive resin composition, which can maintain good water developability and can suppress adhesion and aggregation of dispersion in the developer in a case of repeated use and disposal of the aqueous developer. The water-developable flexographic printing plate precursor of the present invention is a water-developable flexographic printing plate precursor including a photosensitive layer, in which the photosensitive layer contains water-dispersible particles, and the water-dispersible particles have a core containing a polymer and having a glass transition temperature of 0°C or lower and have a shell containing a polymer and having a glass transition temperature of 10°C or higher.
