PROBLEM TO BE SOLVED: To provide a rubber composition which is used for manufacturing a rubber excellent in cutting resistance, and contains a random copolymer in which monomer units of a conjugated diene compound and a non-conjugated olefin are randomly arranged, and a taper copolymer of a conjugated diene compound and a non-conjugated olefin; and to provide a crosslinked rubber composition obtained by crosslinking the rubber composition, and a tire using the rubber composition or the crosslinked rubber composition. SOLUTION: The rubber composition contains a random copolymer in which the monomer units of the conjugated diene compound and the non-conjugated olefin are randomly arranged, and a taper copolymer having at least one block moiety of a block moiety composed of the monomer unit of the conjugated diene compound and a block moiety composed of the monomer unit of the non-conjugated olefin, and a random moiety in which the monomer units of the conjugated diene compound and the non-conjugated olefin are randomly arranged.
