Disclosed is a block copolymer composition for flexographic printing plates, which is capable of providing a flexographic printing plate that has much more excellent wear resistance than conventional flexographic printing plates, while maintaining sufficient rubber elasticity. The block copolymer composition for flexographic printing plates comprises a block copolymer A and a block copolymer B, each of which is an aromatic vinyl-conjugated diene-aromatic vinyl block copolymer having a specific structure, wherein a content of the aromatic vinyl monomer unit in the block copolymer A is 41% or more.
