The Tybee Museum was established in 1961 by The Tybee Island Museum Association. The Association is now known as The Tybee Island Historical Society, a non-profit organization which also operates The Tybee Island Light Station in addition to the Tybee Museum. The purpose of the museum was the same in 1961 as it is today - to interpret the rich history of Tybee Island.
