An object of the present invention is to provide a rubber composition which can further improve abrasion resistance without deterioration in energy efficiency, and a pneumatic tire using the rubber composition. The rubber composition comprises a polymer mixture obtained by modifying a polymer composed of at least one of a conjugated diene compound and an aromatic vinyl compound with a compound having at least one of an ester group and a carboxyl group; at least one of triamines; and silica, the polymer mixture having a weight-average molecular weight of 1.0×10 3 to 1.0×10 5 , and the triamines being a compound represented by the following formula (I): wherein each of R A , R B , R C , R D and R E independently represents a hydrogen atom or an alkyl group, and each of ALK 1 and ALK 2 independently represents an alkylene group.
