A magnetic alignment fixture to temporarily hold a door latch striker in position relative to a door jamb while the alignment of the doors is adjusted. The magnetic alignment fixture includes a base plate of flexible material having an aperture for receiving and positioning the striker. The base plate magnetically holds the striker on the door jamb. The base plate may be moved by sufficient force applied against the striker in the plane parallel to the door jamb to overcome the magnetic force holding the base plate and thereby adjusts the position of the striker. The flexibility of the base plate allows the base plate to be flexibly peeled away from the door jam and the striker in a direction perpendicular to the door jamb after the striker is secured to the door jamb.
