The present invention is to provide an aromatic vinyl-diene copolymer which exhibits excellent mechanical properties and wear resistance when being formed into a tire, a method for producing the aromatic vinyl-diene copolymer, and a rubber composition containing the aromatic vinyl-diene copolymer. The aromatic vinyl-diene copolymer of an embodiment of the present invention is an aromatic vinyl-diene copolymer which is a copolymer of an aromatic vinyl and a diene, wherein the content of a repeating unit derived from an aromatic vinyl is 18 mass % or greater, among repeating units derived from a diene, a proportion of a vinyl structure is 8 mol % or less, a proportion of a 1,4-trans structure is 75 mol % or less, and a proportion of a 1,4-cis structure is from 17 to 90 mol %, and a glass transition temperature is −60° C. or lower.
