This page documents the Tornadoes and Tornado outbreaks of 2007, primarily (but not entirely) in the United States. Most tornadoes form in the U.S., although some events may take place internationally, particularly in parts of neighboring southern Canada during the summer season. Some tornadoes also take place in Europe, e. g. in the United Kingdom or in Germany.

As of December 16, there have been 1,293 reported tornadoes in the U.S. (of which at least 570 have been confirmed), with 82 confirmed fatalities. It is the deadliest year for tornadoes in the U.S. since 1999, when 95 deaths were reported. In addition, three fatalities took place in Mexico, 14 in Chad, one in South Africa, three in Vietnam, one in the Philippines and 25 in China for a worldwide known total of 129.

Notably, the system for classifying tornado damage in the United States changed from the Fujita scale to the Enhanced Fujita Scale on February 1.
