The Ten Pound Island Light is a historic lighthouse in Gloucester Harbor in Gloucester, Massachusetts. It is located on Ten Pound Island, near the eastern end of the harbor. The tower, built in 1881, is a conical cast iron structure 30 feet (9.1 m) tall, replacing a stone tower first built on the site in 1821. The main body is painted white, and the top is painted black.

The tower is the only surviving part of a more extensive light station, which included a keeper's house and an oil house. The island additionally hosted a federal fish hatchery and a Coast Guard air (seaplane) station; only ruins survive.

The lighthouse was listed on the National Register of Historic Places in 1988. Both Winslow Homer and Fitz Henry Lane painted the first tower.
