The 2011 Lockdown was a professional wrestling pay-per-view (PPV) event produced by the Total Nonstop Action Wrestling (TNA) promotion, that took place on April 17, 2011 at the U.S. Bank Arena in Cincinnati, Ohio. It was the seventh event under the Lockdown chronology and the fourth event of the 2011 TNA PPV schedule. In the concept of Lockdown events, every match was booked to take place inside a steel cage.

The event featured double main event in which Sting defeated Rob Van Dam and Mr. Anderson in a steel cage match to retain the TNA World Heavyweight Championship, and Fortune (James Storm, Robert Roode, Kazarian and Christopher Daniels) defeating Immortal (Ric Flair, Abyss, Bully Ray and Matt Hardy) in a Lethal Lockdown match. In the other match at the top of the card Jeff Jarrett defeated Kurt Angle in an "Ultra Male Rules" Two out of Three Falls Steel Cage match.

In October 2017, with the launch of the Global Wrestling Network, the event became available to stream on demand.
