Point Lookout Light is a lighthouse that marks the entrance to the Potomac River at the southernmost tip of Maryland's western shore of the Chesapeake Bay, south of the town of Scotland in Saint Mary's County, Maryland, USA.

On May 3, 1825, the federal government decided that a light was needed at Point Lookout to warn ships of the shoals and to mark the entrance to the Potomac River, and appropriated $1,800 for the project.

Because of the cost overruns for the land purchase, Congress appropriated $4,500 on May 23, 1828, and awarded a contract on July 22, 1830, to John Donahoo for $3,050.

Construction commenced before the deed to the land was obtained and Jenifer Taylor argued with the government until the matter was resolved some 2 years after the lighthouse became operational.

In 1883, the lighthouse was raised to two full stories with a summer kitchen and additional bedroom added at the southwest corner.

Civilians continued to live in the house until 1981, when a dispute over a failing well led to the revocation of a 99-year lease that the state had with the Navy.
