Abstract: A trailer hitch alignment device has a base block for placement on the coupler of a trailer. The block has a magnet at its bottom for being connected to the coupler and a series of apertures directed at varying angles to receive an upright post inclined at a selected angle. A cross arm extending generally horizontally is connected to the post in a manner such as to allow adjustments in vertical and horizontal directions. The post-to-cross arm connection has pair of block members through which the post and cross arm pass and a spring biasing the members together.
