Origin of "Fire Island"
Fire Island—the genesis of its name sparks our imagination.
There are conflicting views as to the origin of the name Fire Island. The island may have been named after Fire Island Inlet, which appeared on a deed in 1789, and the inlet’s name may have started as a simple spelling error.
Under another hypothesis, the name originates from the fires reportedly set by pirates to lure vessels to shore.
Some say poison ivy gave Fire Island its name, either for its red leaves in autumn or its fiery itch.
Regardless of whether any of these hypotheses are true, the name Fire Island has long been applied to the western part of Fire Island. The more easterly part of the barrier island was known as Great South Beach until about 1920, when common usage extended the Fire Island name to the rest of the island.
The true origin of Fire Island’s name is obscure.
