The invention relates to an ejection seat stabilization parachute which comprises a canopy and parachute cords. The canopy comprises a primary top width, a secondary top width and a skirt width whichare connected sequentially from top to bottom, the skirt width bends outwards, a row of evenly distributed crescent holes are formed by stitching the primary top width and the secondary top width at intervals, another row of evenly distributed crescent holes are formed by stitching the secondary top width and the skirt width at intervals, openings of the crescent holes of the upper row are locatedin the upper outer side of the secondary top width, openings of the crescent holes of the lower row are located in the upper outer side of the skirt width, and the crescent holes on the same row areidentical in size. The ejection seat stabilization parachute is small in parachute opening forces, rapid in stabilization, high in stabilization, lightweight and simple in manufacture.
