The Lincoln Rock Lighthouse was a lighthouse located on Lincoln Island, a small islet in Clarence Strait in southeastern Alaska, United States.

The original lighthouse was built in 1903 and was abandoned in 1909 after being damaged by a storm.

In 1911 a manned fog signal station was built on Lincoln Island about 440 yards from the rock, and in 1944 a skeletal light tower was added.

The lighthouse was later demolished and only the foundation of the buildings remain.
