Provided is a lithographic printing plate precursor that gives good scratch resistance without impairing printing durability, chemical resistance and on-press developability. On a support, at least one selected from (A) a repeating unit containing a condensed ring structure of an alicyclic hydrocarbon in a side chain, a hydroxy group, an amino group, an amide group, a sulfonic acid group, and an alkylene oxide chain. A binder polymer containing a repeating unit containing one hydrophilic group in the side chain and a repeating unit containing a cyano group in the side chain, (B) organic polymer fine particles, (C) a radical generator, (D) an infrared absorber, and ( E) an image recording layer containing a radically polymerizable compound, (A) a combination of a repeating unit containing a condensed ring structure in the side chain and a repeating unit containing a hydrophilic group in the side chain in the binder polymer is a specific condition An on-press developable lithographic printing plate precursor.
