An object of the present invention is to provide a multicomponent copolymer for use for producing a rubber composition and a rubber product having high abrasion resistance and wet performance. Further, the invention is to provide a rubber composition containing the multicomponent copolymer, a crosslinked rubber composition produced by crosslinking the rubber composition, and a tire and a rubber product using the rubber composition or the crosslinked rubber composition. The multicomponent copolymer of the invention contains a conjugated diene unit, a non-conjugated olefin unit and an aromatic vinyl unit, wherein the content of the aromatic vinyl unit is 5 mol% or more and less than 50 mol% of the whole multicomponent copolymer and the content of the non-conjugated olefin unit is more than 0 mol% and 50 mol% or less of the whole multicomponent copolymer.
