The 2013 Lockdown was a professional wrestling pay-per-view (PPV) event produced by the Total Nonstop Action Wrestling (TNA) promotion, which took place on March 10, 2013, at the Alamodome in San Antonio, Texas. It was the ninth under the Lockdown chronology and second event in the 2013 TNA PPV schedule. At 7,200 fans, the event became TNA’s most domestically attended event, beating their previous record from Slammiversary 2012. It would hold the record for over a decade until it was broken at Slammiversary 2025.

From 2005 to 2012, the theme of Lockdown events featured every match taking place inside a Steel Cage. Beginning with this year's event, Lockdown was modified to featuring standard matches, and cage matches were reserved only for the high profile bouts. Lockdown was also moved to March for the first time since its inception in 2005. Eight matches were featured on the card. In the main event, Bully Ray defeated Jeff Hardy in a Steel Cage match for the TNA World Heavyweight Championship.

In October 2017, with the launch of the Global Wrestling Network, the event became available to stream on demand. It would later be available on Impact Plus in May 2019.

During the November 29, 2012 Impact Wrestling episode, the location and date for the ninth annual Lockdown event were announced as the Alamodome in San Antonio, Texas on March 10, 2013. In a press release, TNA President Dixie Carter stated, "We have been waiting to play San Antonio until we could bring this great city a big televised event." Tickets for the event went on sale on December 7, 2012.

From January to March 2013, the Road to Lockdown Tour, which TNA holds every year, toured many different cities across the United States and United Kingdom for live events and TV tapings to build up to the Lockdown event. As part of TNA's business initiative to reduce the number of pay-per-views produced per year, Lockdown was moved to March, leaving Genesis, Lockdown, Slammiversary and Bound for Glory as the remaining live PPVs on their schedule. Like every year, TNA arranged their Lockdown VIP Weekend featuring their fan-friendly Lockdown Fanfest, giving the opportunity to fans to get close with their favorite wrestlers for autographs, photographs and conversations on March 9, 2013, a day before the event.

Lockdown featured eight professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches.

The main event headlining Lockdown was Bully Ray facing defending champion Jeff Hardy in a Steel Cage match for the TNA World Heavyweight Championship. On the February 14, 2013 edition of Impact Wrestling, the number one contender to the TNA World Heavyweight Championship at Lockdown was determined through a tournament designed to allow the competitors to impress TNA General Manager Hulk Hogan, enabling him to personally select the number one contender. Out of the four matches scheduled, two resulted in a no-contest (Kurt Angle versus Samoa Joe and Bobby Roode versus Austin Aries). In the other matches, Magnus defeated Christopher Daniels and James Storm beat Rob Van Dam. Meanwhile, Brooke Hogan spoke with her father, Hulk Hogan, about her husband Bully Ray wanting to compete for the championship, which Hulk said he would take under advisement. On the same night, before a decision regarding the title contender could be made, the Aces & Eights gang halted the announcement by surrounding Hogan for an attack, but retreated when Bully Ray and Sting came to Hogan's aid with weapons. The next week, in a decision seen as an act of nepotism, Hogan chose his son-in-law Bully Ray, who did not partake in the tournament, as the number one contender to the World Title, disregarding the actual competitors in the tournament.

The ninth annual Lethal Lockdown match took place at Lockdown to showcase the main feud in TNA. This year, for the first time, instead of the cage ceiling (with weapons attached) lowering to indicate the start of the final phase of the Lethal Lockdown match, weapons were brought to the match, where pinfalls and submissions were legal ways to win once all participants had entered. For over 9 months, the masked gang Aces & Eights, beginning with their attacks on Sting and Hulk Hogan, had waged war against TNA and the company's roster through a mixture of all-out brawls and calculated attacks. After holding Sting and Hogan for ransom (in a deal to free attorney Joseph Park, who worked for Hogan to investigate the mysterious gang), Aces & Eights received their chance to win "full access" to the promotion after defeating Sting and Bully Ray on October 14 at Bound for Glory, where a major member of the biker gang was revealed to be Devon, who later cited his groupies, a contract dispute, the anonymous leader of the group who patched him in, and Bully Ray mistreating him and his children in the past as his reasons for joining. Over the next few months, the unmasking and revelations of Aces & Eights members occurred leading to Aces & Eights challenging the TNA roster to "a war to end all wars" at Lockdown. In the following weeks, Aces & Eights assembled their team, captained by Devon. Along with Devon, this team included D.O.C., Mr. Anderson, Knux and Garett Bischoff, and they were to fight against Team TNA captained by Sting which was revealed to include James Storm, Samoa Joe, Magnus, and a returning Eric Young, who was injured months ago by the Aces & Eights.
