Tornadoes in the U.S. state of Alaska are extremely rare, with only six tornadoes ever recorded within state boundaries. Out of the six tornadoes to ever hit, all were rated FU, EFU, F0 or EF0, and none have caused significant damage or injuries.

Thunderstorms are fairly rare in most of Alaska, but do occur in the interior in the summer with some frequency and may cause wildfires. Anchorage gets a thunderstorm every few years. There has even been the rare thunderstorm in Utqiaġvik on the Arctic coast. While weak tornadoes and waterspouts, while extremely rare, do sometimes occur, Alaska is considered the least tornado-prone state in the United States.^[1]
