New London Ledge Lighthouse is a lighthouse on the Thames River in the U.S. state of Connecticut, at the mouth of New London Harbor. It was built in 1909 in the Second Empire style and was automated in 1987. In 1990, it was added to the National Register of Historic Places. The lighthouse is owned and maintained by the New London Maritime Society as part of the National Historic Lighthouse Preservation Act program.

New London Ledge Lighthouse was built in 1909 on the southwest ledge at the mouth of New London Harbor. It was originally called the Southwest Ledge light, but this caused confusion with Southwest Ledge Light in New Haven, Connecticut, so it was renamed New London Ledge Light in 1910. The United States Coast Guard took over in 1939 upon its merger with the Lighthouse Service, and the light was automated in 1987. The original fourth order Fresnel lens was removed and was later put on display in the New London Customhouse museum. The light was added to the National Register of Historic Places in 1990.

Ledge Light has long been the subject of a ghost legend, centering around the supposed spirit of a former keeper named Ernie. The lighthouse has been featured on paranormal reality shows such as Scariest Places on Earth and Ghost Hunters. Investigators from The Atlantic Paranormal Society concluded on Ghost Hunters that there was not enough evidence to determine any paranormal activity taking place at the lighthouse, despite a few unexplained phenomena such as cold spots.
