The present invention relates to a photochromic curable composition suited for the production of a photochromic cured product having excellent optical properties such as a high refractive index and a large Abbe's number, having favorable photochromic properties such as a large color density, and having good fatigue resistance, and to a photochromic lens obtained by curing the photochromic curable composition. The photochromic curable composition is characterized by comprising 100 parts by weight of a polymerizable monomer containing at least 10% by weight of a sulfur-containing (meth)acrylate polymerizable monomer represented by the following general formula (1),
wherein R1, R2 and R3 may be the same or different and are hydrogen atoms or methyl groups, and n is an integer of 1 to 10,
and 0.001 to 10 parts by weight of a photochromic compound.
