The South Indian Derby, also known as the Southern Derby, is the name given to a football derby contested by any two of the three professional football clubs from South India—Bengaluru FC, Chennaiyin FC and Kerala Blasters FC. The geographical proximity of the clubs contributes significantly to the rivalries. Along with this, the competition between the West Block Blues and Manjappada—the fan clubs of Bengaluru FC and the Blasters respectively—intensifies the rivalry among those two clubs.
