Lockdown is a professional wrestling event held by the American professional wrestling promotion Impact Wrestling (formerly Total Nonstop Action Wrestling (TNA)). It was considered one of the flagship events in the company, alongside Slammiversary and Bound for Glory. The event was created in 2005 and is highlighted by the premise that all matches take place inside a steel cage. In addition to the cage, the event usually features additional gimmicks added on to the steel cage stipulation. Trademark Lockdown specialty matches include the Lethal Lockdown, Xscape matches and, exclusive to the Knockouts division, the Queen of the Cage match.
