The Graves Light is a lighthouse located on The Graves, the outermost island of the Boston Harbor Islands National Recreation Area, and some 11 miles offshore of downtown Boston, Massachusetts, USA. At 113 feet tall, it is the tallest lighthouse in the approaches to the Port of Boston, and is an important navigation aid for traffic to and from the port.cite web| title = The Graves Factsheet | url = http://www.bostonislands.org/factsheet_template.asp?rsIslands__MMColParam=grav | publisher = Boston Harbor Islands Partnership | accessdate = August 3 | accessyear = 2006]

Graves Light is the setting for the climactic storm in the 1948 film "Portrait of Jennie".

The lighthouse was built in 1905, to a conical design using granite blocks on a granite foundation, and equipped with a first-order Fresnel lens. Operated by the United States Coast Guard, the light was automated in 1972 and has a signature of two white flashes every 12 seconds.cite web| title = Historic Light Station Information & Photography - Massachusetts | url = http://www.uscg.mil/hq/g-cp/history/WEBLIGHTHOUSES/LHMA.html | publisher = United States Coast Guard | accessdate = August 5 | accessyear = 2006] cite web| title = Graves Lighthouse, Boston Harbor, Massachusetts | url = http://www.lighthouse.cc/graves/index.html | publisher = www.lighthouse.cc | accessdate = August 5 | accessyear = 2006]
