This invention provides a modified natural rubber producible at a lower cost than the conventional techniques and capable of improving the low loss factor, wear resistance and fracture characteristics of the rubber composition using the modified natural rubber as the rubber component in the rubber composition, and a method for producing the modified natural rubber. This invention provides a modified natural rubber formed by adding a hydrazide compound having a polar group to at least one natural rubber raw material selected from the group consisting of a natural rubber, a coagulated natural rubber latex and a natural rubber cup lump, a rubber composition using the modified natural rubber, and a tire using the rubber composition in any tire member.
