A method and an apparatus for controlling a rolling mill which dampens a snake motion of a material being rolled is disclosed. According to this method and apparatus, an amount corresponding to the snake motion of the material being rolled is detected, and the value thus detected is added to a value corresponding to a differentiated value of said detected value. A control operation is applied to the material being rolled to thereby control the snake motion of the material.
