}} Seung-Hui Cho (, Korean name ordering Cho Seung-hui;}} January 18, 1984 – April 16, 2007) was a South Korean mass murderer responsible for the Virginia Tech shooting in 2007. Cho killed 32 people and wounded 17 others with two semi-automatic pistols on April 16, 2007, at Virginia Tech in Blacksburg, Virginia. This killing is the deadliest school shooting in U.S. history, and was at the time the deadliest mass shooting in U.S. history.|name=surpassed}} A senior-level undergraduate student (creative writing) at the university, Cho died by suicide after police breached the doors of Virginia Tech's Norris Hall which Cho had locked with heavy chains, where most of the shooting had taken place.

Born in South Korea, Cho was eight years old when he immigrated to the United States with his family. He became a U.S. permanent resident as a South Korean national. At the time of the shooting, Cho had the legal status of resident alien. In middle school, he was diagnosed with a severe anxiety disorder with selective mutism, as well as major depressive disorder. After his diagnosis, he began receiving treatment and continued to receive therapy and special education support until his junior year of high school. Cho was bullied throughout high school. During Cho's last two years at Virginia Tech, several instances of his abnormal behavior, as well as plays and other writings he submitted containing references to violence, caused concern among teachers and classmates.

In the aftermath of the shootings, Virginia Governor Tim Kaine convened a panel consisting of various officials and experts to investigate and examine the response and handling of issues related to the shootings. The panel released its final report in August 2007, devoting more than 20 pages to detailing Cho's troubled history. In the report, the panel criticized the failure of the educators and mental health professionals who came into contact with Cho during his college years to notice his deteriorating condition and help him. The panel also criticized misinterpretations of privacy laws and gaps in Virginia's mental health system and gun laws. In addition, the panel faulted Virginia Tech administrators in particular for failing to take immediate action after the first two deaths of Emily J. Hilscher and Ryan C. "Stack" Clark. Nevertheless, the report did acknowledge that Cho must still be held primarily responsible for the killing, despite his "emotional and psychological disabilities [having] undoubtedly clouded his own situation".
