A door reminder for hanging on a doorknob for delivering a message comprising a hanger, a flap and at least one electronic device to be actuated by the flap. The hanger is provided with a hanger opening for hanging the door reminder on the shank of the doorknob. The flap is rotatably and horizontally mounted on the hanger above the hanger opening and the flap is provided with a flap opening such that the doorknob can pass through the flap opening when the flap is rotated towards the surface of the hanger hanging on the shank of the doorknob through the hanger opening with the hanger located between the door and the flap. The flap is maintained at an operative angle of approximately 30 degrees above the front surface of the hanger by an urging component when the flap is not moved. Preferably the door reminder includes two electronic devices, one light emitting and one sound emitting. The two electronic devices are controlled by a switch component constructed to be actuated by the rotational movement of the flap when the flap is moved by a hand. The door reminder may further include a non-electrical display component for delivering message to people.
