A safety door stopper for use in trip, including a wedge stopper block and a coupler member. The coupler member is used to fix the wedge stopper block under a lower edge of the door board. A bottom face of the wedge stopper block is disposed with an unsmooth face. When the wedge stopper block is fixed under the lower edge of the door board, the unsmooth face is able to enlarge the frictional coefficient between the door board and the ground and enlarge the frictional force. Therefore, the resistance against the door board is increased to make it difficult to push open the door board and ensure safety in trip.
