A circuit for accomplishing electron beam convergence in a color cathode ray tube, which comprises a first circuit arrangement for producing a first misconvergence correcting voltage with which dynamic misconvergence in the horizontal direction appearing every horizontal period on the display panel of a color cathode ray tube can be corrected independently in both the left and right sides of the display panel when it is supplied to a deflecting device provided for deflecting electron beams in the color cathode ray tube and its amplitude is adjusted, a second circuit arrangement for producing a second misconvergence correcting voltage with which dynamic misconvergence in the horizontal direction appearing every vertical period on the display panel can be corrected independently in the top, middle and bottom portions of the display panel when it is supplied to the deflecting device and its amplitude is adjusted, and an additional circuit arrangement for supplying the first and second misconvergence correcting voltages to the deflecting device.
