The present invention relates to a seedling transplater. The purpose of the present invention is to provide a seedling transplanter which enables a user to grasp the seedling transplanter with one hand and inject a seedling with the other hand to plant the seedling thereby allowing fast work to be achieved without an additional worker and minimizing soil pushed away from the side portions of the seedling by the seedling transplanter during planting so that the seedling can be planted upright. To this end the seedling transplanter of the present invention comprises: a first rod and a second rod which are bar shaped are provided with grips on the upper portions thereof and are hingedly coupled together a first side plate which is located in the lower portion of the first rod of which the rear portion is closed and is inclined inward toward the lower portion thereof and a second side plate which is located in the lower portion of the second rod of which the rear portion is closed and is inclined inward toward the lower portion thereof so that the rear portion and the bottom portion thereof face the bottom portion of the first side plate wherein the front portions of the first side plate and the second side plate are open.
