A process for producing a modified conjugated diene based polymer includes a step (a) of reacting a silicon compound with a conjugated diene based polymer having an active end so that the reaction takes place at the active end, the silicon compound having a protected primary amino group in the molecule thereof and a silicon atom to which a hydrocarbyloxy group and a reactive group are bonded, to thereby modify the active end, and a step (b) of performing condensation reaction, in the presence of a titanium compound serving as a titanium-based condensation-accelerating agent. A rubber composition contains the modified diene polymer, and a tire is produced from the rubber composition.
