Cape St Claire is an established residential community on the Broadneck Peninsula in Anne Arundel County, bordered by the Magothy River and the Chesapeake Bay. Developed as a planned community during the mid-20th century, it has grown into a neighborhood known for wooded streets, mature landscaping, waterfront areas, and a mix of longtime and newer homes. Its location near the water and its distinct community character set Cape St Claire apart from nearby Annapolis and other Broadneck Peninsula neighborhoods.
