The invention discloses a folding chopping board comprising a board body and a handle. The board body comprises a triangular base plate, a first folded plate and a second folded plate, each of the first folded plate and the second folded plate is of a triangular structure, and the first folded plate and the second folded plate are respectively connected to two side edges of the triangular base plate through hinges; and the handle comprises a first handle unit and a second handle unit, and the first handle unit and the second handle unit are respectively connected to top edges of the first folded plate and the second folded plate through hinges. In the folding chopping board, when the first folded plate and the second folded plate are oppositely folded, the first handle unit and the second handle unit are oppositely folded, the planar chopping board can be folded to form a dustpan structure with baffle plates at two sides, and therefore cut vegetables on the chopping board can be poured into a pan conveniently. The folding chopping board is simple in structure, and is convenient and practical.
