The Magothy River runs through Anne Arundel County in the U.S. state of Maryland. It is located south of the Patapsco River and north of the Severn River. There are two public park paddling access points, Beachwood Park on the north shore a half mile east of the Magothy Bridge Road bridge, and Spriggs Farm Park off Bayberry Drive, on the south shore two miles west of the Magothy's mouth. Both are Anne Arundel County parks.
