Provided are a modified cellulose fiber-containing rubber composition and rubber composition for tires that are allowed to simultaneously achieve excellent rigidity, excellent tensile properties, and low energy loss by improving the dispersibility of the cellulose fiber in rubber, as well as a pneumatic tire formed from the rubber composition, having excellent handling stability, excellent rolling resistance properties, and excellent durability. The present invention relates to a modified cellulose fiber-containing rubber composition containing: a modified cellulose fiber (A) obtained by adding a C15 or higher cyclic polybasic acid anhydride (a) containing a hydrophobic group to a cellulose fiber through esterification; a dispersing polymer (B) having a softening point of 135°C or lower; and a rubber component (C).
