# List of people who disappeared mysteriously at sea

Throughout history, people have mysteriously disappeared at sea, many on voyages aboard floating vessels or traveling via aircraft. The following is a list of known individuals who have mysteriously vanished in open waters, and whose whereabouts remain unknown. In most ocean deaths, bodies are never recovered, but this fact alone does not make their disappearance mysterious. For example, the victims of the RMS Titanic disaster are not considered to have disappeared mysteriously at sea.
