List of tornadoes rated on the 2018 International Fujita scale
This is a list of tornadoes that have been rated officially or unofficially on the International Fujita scale (IF-scale). The International Fujita scale was drafted in 2018 by the European Severe Storms Laboratory (ESSL) along with multiple European meteorological agencies. As of 2023, the scale is not officially published for use, however, various tornadoes have received official/unofficial ratings under the scale. Since the scale is not officially in use, official ratings can only come from published academic papers or analyses from a government meteorological agency or from the European Severe Storms Laboratory and their partners. On May 6th, 2023, version 0.99.9d was published, which changed it to a 9-step rating scale. This replaced the 12-step scale used to rate tornadoes on this list. List 
At least 40 tornadoes received an official or unofficial rating on the 2018 draft version of the International Fujita scale, with official ones in the Czech Republic, Denmark, Italy, Russia, Greece, Germany, Turkey, Poland, Norway, Sweden, Netherlands, Cyprus, Spain, Slovak Republic, and in France, and two unofficial ones in the United States.
