The invention discloses a two-dimensional micromotion stage, which comprises a substrate (1), a worktable (12) connected with the substrate (1) by a plurality of flexible hinges, an X-direction lever amplification mechanism (3) which is connected with the worktable (12) and comprises an X-direction lever (2) and a Y-direction lever amplification mechanism (5) which is connected with the worktable(12) and comprises a Y-direction lever (4). The X-direction lever amplification mechanism (3) and the Y-direction lever amplification mechanism (4) are respectively provided with drivers (6). By symmetrical arrangement of the structure and rigidity symmetrical design of the flexible hinges, the X-direction and the Y-direction both reach excellent decoupling effect, the difficulty of ultraprecise motion control is reduced, the motion amplification ratio is improved when the coupling is reduced, the working stroke of the micromotion stage is enlarged; the X-direction and Y-direction driving realizes two-dimensional motion in the same plane; and the two-dimensional micromotion stage has compact structure and is beneficial for implementation.
