The invention discloses a method and system for predicting the cross stiffness of a rolling mill, a three-dimensional numerical model of a rolling mill roll system and the rolling mill is established according to a roll system position measurement result, the input of the three-dimensional numerical model is a roll system space state and rolling pressure, and the output of the three-dimensional numerical model is the stiffness of the rolling mill; performing a finite element simulation experiment by adopting an orthogonal test method to obtain the rigidity of the rolling mill on the operation side and the working side under the influence of different horizontal factors; the positions of all lining plates of the rolling mill measured on site, the rolling pressure value and the rolling mill rigidity value are mixed with orthogonal simulation experiment data, and the mapping relation between the spatial position of a roller system and the rolling mill rigidity is learned through a neural network; and measuring t
