Prehistoric tsunamis are tsunamis and so-called "megatsunamis" that occurred before recorded history. The events have been identified through oral tradition and/or geological evidence. Those events that have been identified through contemporary records are listed as historic tsunamis.
List edit

| 35.5 million years BP | Chesapeake Bay | bolide impact | presumed [3] |
| 10,000 yrs BP | Seton Portage, British Columbia | landslide into lake | presumed[4] |
| 8,000 years BP | Mount Etna, Sicily | volcanic landslide | submarine sediments off Etna, submerged settlements off eastern Mediterranean coast, e.g. Atlit Yam[5][6] |
