The tornado outbreak of April 10–11, 2001, was a large tornado outbreak which affected the central Great Plains on April 10–11, 2001. During the two-day outbreak, it produced a total of 79 tornadoes across eight states including Kansas, Missouri, Oklahoma, Texas, Nebraska, Iowa, Illinois and Michigan. Four people were killed, 18 injured, and more than $23 million in damage was reported. The fatalities were reported in Oklahoma, Iowa and Missouri including two from a single tornado in Wapello County, Iowa.

The strongest tornado tracked for over 75 miles from northern Missouri to near Des Moines, Iowa causing extensive damage to several structures. In addition to that storm, a supercell on April 10 produced the largest and most damaging hail swath in history; as well as ten tornadoes.

The first tornadoes developed during the late afternoon across west-central Missouri and mostly tracked near Interstate 70 eastward towards the St. Louis Metropolitan Area during the first half of the evening before weakening in Illinois. In addition to the damaging hail (see Tri-State hailstorm section for details), several weak tornadoes were confirmed. One tornado, however, killed a person inside a mobile home near the Fulton area in Callaway County

A new wave of tornadoes touched down further to the west in Nebraska, Kansas, Oklahoma and Texas during the late evening and overnight hours. One person was killed in Coal County, Oklahoma by an F2 tornado that threw the mobile home for about 200 yards before being destroyed. Several other significant tornadoes also caused extensive damage across southern Oklahoma, northern Texas and both the Oklahoma and Texas Panhandles until activity slowed down after dawn on April 11.
