Gloucester Harbor is a late 19th-century painting by American artist William Morris Hunt.

Done in oil on canvas, the impressionist painting depicts morning in the harbor of Gloucester, a major fishing port in New England.

The painting was one of Hunt's first forays into the school of impressionism, and the creation of Gloucester Harbor and several other impressionism-inflected works sparked Bostonian interest in the impressionist movement.

The painting is currently on display at the Museum of Fine Arts.
