This is a list of tornadoes which have been officially or unofficially labeled as F4, EF4, IF4, or an equivalent rating. These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path.

Tornadoes are among the most violent known meteorological phenomena. Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe. In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale. The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. F4 tornadoes were estimated to have had maximum winds between and

Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale. Ultimately, a new scale was devised that took into account 28 different damage indicators; this became known as the Enhanced Fujita scale. With building design and structural integrity taken more into account, winds in an EF4 tornado were estimated to between and . The Enhanced Fujita scale is used predominantly in North America. Most of Europe, on the other hand, uses the TORRO tornado intensity scale (or T-Scale), which ranks tornado intensity between T0 and T11; F4/EF4 tornadoes are approximately equivalent to T8 to T9 on the T-Scale. Tornadoes rated IF4 on the International Fujita scale are also included on this list.

List of F4/EF4 tornadoes The most recent F4/EF4 tornado occurred on August 8, 2026, and occurred near the municipality of Piraí Do Sul, Brazil.

Pre-1950 The National Weather Service in the United States did not rate any tornadoes prior to 1950. Other organizations like the European Severe Storms Laboratory (ESSL) and Environment and Climate Change Canada (ECCC) on the other hand, did rate tornadoes prior to 1950. The only violent tornado that impacted the United States prior to 1950 and has an official rating is the 1946 Windsor–Tecumseh tornado, which received a rating from ECCC. However, the impact to the United States remains officially unrated.
