The present invention relates to a laser-engravable flexographic printing original plate in which an increase in time required for entire surface curing is suppressed while benefiting from a decrease in plate surface tackiness due to blending of the silicone compound. A laser-engravable flexographic printing original plate obtained by irradiating a molded product made of a photosensitive resin composition with light so as to cross-link and cure the molded product, in which the photosensitive resin composition contains a water-dispersible latex, a photopolymerizable unsaturated compound, a photopolymerization initiator, and a silicone compound having an amino group in the molecule. When the water-dispersible latex is selected from polybutadiene rubber and poly(nitrile-butadiene) rubber, the silicone compound has a refractive index of 1.44 to 1.60. When the water-dispersible latex is poly(styrene-butadiene) rubber, the silicone compound has a refractive index of 1.47 to 1.63.
