Abstract: A portable door stop comprising a wedge shaped unit, a first arm, and second arm. The wedge shaped unit has a tapered front end and an enlarged back end and tapers from the back end to the front end. The first arm and the second arm extend away from the wedge shaped unit and are configured for being removably engageable to each other to form a loop. The wedge shaped unit is configured for being pushed in a gap between a door and a floor under the door to prevent the door from moving, while the first and second arms are configured for enabling the portable door stop to be removably joined to a desired object by forming the loop around a portion of the desired object.
