The execution of Robert Van Hook occurred on July 18, 2018, at the Southern Ohio Correctional Facility in Lucasville, Ohio. Van Hook was executed via lethal injection for the 1985 murder of 25-year-old David Self. His case achieved notoriety because of his failed gay panic defense. Ultimately, his conviction was upheld by the U.S. Supreme Court and Governor John Kasich of Ohio rejected his bids for clemency.

Capital punishment is a legal penalty in the U.S. state of Ohio, although all executions have been suspended indefinitely by Governor Mike DeWine until a replacement for lethal injection is chosen by the Ohio General Assembly. The last execution in the state was in July 2018, when Robert J. Van Hook was executed via lethal injection for murder.
