A pile lighthouse is a type of lighthouse found in Australia, the United Kingdom and United States. In the United States they are found primarily in Florida, including on open reefs adjacent to the Florida Keys.

The pile lighthouses on the reefs in Florida are tall skeletal towers, with living and working quarters set high above the reach of storm waves. Some of the lights were converted screw-pile lighthouses, while others were built on piles driven directly into the sea bed.
