A door prop device for the purpose of maintaining a hinged door in a propped-open position against the forces of spring tension, wind, gravity, or other causes, which will effectively function without damaging either the door or any adjacent structure and which will function on doors which pivot on vertical axes, horizontal axes, or any pivot axes orientations between vertical and horizontal. The device comprises a block-shaped prop member and a retainer member attached to the prop member. The retainer member is adapted to be placed over and engage with a hinge pin of an opened door hinge whereby the prop member is caused to assume an obstructing position in the space between the separated plates of the opened hinge. When it is desired to close the door, the door prop device is simply removed from the hinge and the door may then be closed.
