The invention relates to high-strength strip steel with high surface quality and a production method and application thereof, and belongs to the technical field of hot-rolled strip steel preparation. The method comprises the steps that a steel billet is heated, and the tapping temperature of heating ranges from 1165 DEG C to 1195 DEG C; carrying out rough rolling on the heated steel billet to obtain an intermediate billet; the intermediate billet is subjected to finish rolling and then cooled, and the high-strength strip steel is obtained; and the tapping temperature of heating is controlled to be 1165-1195 DEG C, so that the influence on the surface quality of the strip steel caused by too thick raw iron sheets in the furnace is avoided, and the problem that the surface quality of the high-strength strip steel is poor at present is solved.
