The present invention provides a learning method of rolling load prediction which uses a prediction error of a rolling load at an actual pass of a stock in hot rolling to correct a predicted value of rolling load at a subsequent rolling pass. The method comprises changing a gain for multiplying with the prediction error of the rolling load at the actual pass in accordance with a thickness of the stock to thereby set the learning coefficient of the rolling load prediction and improve the precision of the prediction.
