This page documents the tornadoes and tornado outbreaks of 2011. Extremely destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season, and somewhat regularly in Europe, Asia, and Australia.
There were 1,721 tornadoes confirmed in the United States in 2011, which was the third highest on any year on record, with only 2024 and 2004 having more confirmed tornadoes. Unlike 2004 and 2024 (which saw more tornadoes than fatalties), 2011 was a catastrophic and an extremely deadly year for tornadoes; worldwide, at least 577 people perished due to tornadoes: 12 in Bangladesh, three in Russia and Japan, two in South Africa, one each in New Zealand, the Philippines, Greece and Canada, and 553 in the United States (compared to 564 deaths in the prior ten years combined). Due mostly to several extremely large tornado outbreaks in the middle and end of April and in late May, the year finished well above average in almost every category, with six EF5 tornadoes and nearly enough total tornado reports to eclipse the mark of 1,817 tornadoes recorded in 2004, the current record year for total number of tornadoes.
The 553 confirmed fatalities marks the second-most tornadic deaths in a single year in U.S. history, behind only 1925 in terms of fatalities attributed to tornadic activity. Most of the damage and over two-thirds of the total fatalities in 2011 were caused by a late-April Super Outbreak (more specifically a single EF5 claiming 71 lives and an EF4 claiming 64 lives in the state of Alabama) and an EF5 tornado that struck Joplin, Missouri, in late May, becoming the costliest tornado on record.
