The first lighthouse was established in 1835 to mark the entrance to Rockport Harbor.
The lighthouse was rebuilt in 1851 and again in 1896.
A 6th order Fresnel lens was installed in the lantern in 1857.
The current Victorian-styled keeper house was built in 1878 and is similar to the one on Thacher Island.
In 1932 the light was converted from white to green.
The Coast Guard moved the station to shore at Gap Head and sold the island to private parties in 1934.
The Coast Guard continues to maintain the light as an official aid to navigation today. In 1967 the island (except for the lighthouse) was donated to Massachusetts Audubon Society who maintains it as a wildlife sanctuary.
Straitsmouth Island was listed on the National Register of Historic Places in 1987.
In 2010 the lighthouse and 1.8 acres of land was given to the Town of Rockport by the Coast Guard.
In 2014 the Town of Rockport signed a 30 year lease with Mass Audubon for the use of the keeper and oil houses.
