Palmer Island Light Station is a historic lighthouse in New Bedford Harbor in New Bedford, Massachusetts, USA.[2][3] The lighthouse was built in 1849 out of stone rubble. It was discontinued when the harbor's hurricane barrier was built in the early 1960s, as its location immediately north of the barrier was no longer an outlying danger and there are lights on either side of the barrier opening.
From 1888 until 1891 it served, with Fairhaven Bridge Light, as a range light to guide vessels past Butler Flats, a rocky shoal on the west side of the entrance channel.
