Point Retreat Light is a lighthouse located on the Mansfield Peninsula at the northern tip of Admiralty Island in southeastern Alaska, United States. It provides aid in navigation through the Lynn Canal.

Point Retreat was named by Joseph Whidbey on July 19, 1794, because of his need to retreat from local Tlingit.

Point Retreat was set aside as a 1,505-acre (609 ha) lighthouse reserve in 1901 by executive order of President William McKinley, but the point had to wait for its lighthouse due to inadequate funding. Point Retreat was first lit in 1904 and displayed a fixed white light. The first Point Retreat Lighthouse was a six-foot-tall hexagonal wooden tower, topped by a hexagonal lantern room. In 1917, Point Retreat was stripped of its personnel and downgraded to a minor light until 1924, when a new combination lighthouse and fog signal was built. The lantern was removed in the 1950s and a solar-powered 300 mm lens was installed on a post attached to the tower. In 1973 the light was again unmanned and downgraded to a minor light again.

In 2003 the light was added to the National Register of Historic Places.
