A modified high-cis isoprene polymer, a method for producing the same, and a tire containing the aforementioned polymer are provided. A polymerization reaction is performed on isoprene monomers in an organometallic catalyst system to form a high-cis isoprene polymer having an organometallic active site, wherein the organometallic active site is formed by an organometallic catalyst system. The high-cis isoprene polymer having the organometallic active site is reacted with a modifier mixture including a first modifier and a second modifier via the organometallic active site. The first modifier and the second modifier are compounds represented by formula 1 and formula 2, respectively: X-R1-Si(R2)3 formula 1, and R3-Si(R4)3 formula 2, wherein X, R1, R2, R3, and R4 are defined in the specification.
