The disclosure is of conveyor belt tracking apparatus comprising an endless conveyor belt having a right edge and a left edge and supported on rollers on which the belt is driven along a predetermined path. First and second rollers are provided under the belt adjacent to the left and right edges and sensing switches are provided adjacent to the left and right edges. The sensing switches are coupled to and turn on a motor having a drive shaft whose direction of rotation pivots the first and second rollers in the proper direction to bear against the belt to move it to the right or left to compensate for undesired belt movement to right or the left and to return the belt to the predetermined path.
