The Northwest Passage Light was a lighthouse located eight miles (13 km) from Key West, Florida, at the entrance to the northwest channel to the Key West harbor. The first light was a lightship put on station in 1838. It is not known if the lightship survived the Great Havana Hurricane of 1846, which destroyed the Sand Key and Key West lighthouses. The United States Lighthouse Board requested funds to replace the lightship in 1852, citing the expense of maintaining it.
