Jack Hensley (September 22, 1955 – September 21, 2004) was an American engineer from Marietta, Cobb County, Georgia, near Atlanta.
While working in Iraq he was kidnapped and beheaded by Iraqi insurgents. His colleague, Eugene Armstrong, was beheaded the previous day. Hours after Hensley was beheaded, Tawhid and Jihad posted a videotape on the Internet of British hostage Kenneth Bigley pleading to then Prime Minister Tony Blair to have his life spared. Bigley was beheaded three weeks later, on October 8, 2004.
