Abstract: An automatic gravity-actuated mailbox indicator is adapted for use in combination with a mailbox including a housing with an access opening for receiving mail and a pivoted door for closing the access opening. The mailbox indicator includes a conspicuous object adapted for being viewed from a distance. A supporting stem extends from the object, and has a free end for being wedged between the pivoted door and housing of the mailbox with the door in a closed position. The object is temporarily held at an elevated location relative to the mailbox housing. The mailbox indicator is actuated by gravity upon movement of the pivoted door from the closed position to an open position, such that the object falls from the elevated location to a lowered location thereby providing a readily visible indication of an opening of the pivoted door.
