The 2019 Super ShowDown was the second annual Super ShowDown professional wrestling pay-per-view (PPV) and livestreaming event produced by the American company WWE. It was held for wrestlers from the promotion's Raw, SmackDown, and 205 Live brand divisions. The event took place on June 7, 2019, at the King Abdullah Sports City's King Abdullah International Stadium in Jeddah, Saudi Arabia. It was the third event that WWE held in Saudi Arabia under a 10-year partnership in support of Saudi Vision 2030.

Ten matches were contested at the event, including one on the Kickoff pre-show. In the main event, The Undertaker defeated Goldberg in what was their first and only match against each other. Other prominent matches saw Seth Rollins defeat Baron Corbin to retain Raw's Universal Championship in the opening bout, Shane McMahon defeated Roman Reigns, Kofi Kingston defeated Dolph Ziggler to retain SmackDown's WWE Championship, and Randy Orton defeated Triple H; this was Triple H's final match to take place on a PPV and in front of a live crowd before having to retire in 2022 due to a cardiac event. The event was also notable for having WWE's largest standard battle royal with a total of 51 participants, though originally scheduled for 50. It was won by Mansoor, a WWE rookie from Saudi Arabia who signed with the company following 2018's Greatest Royal Rumble event and had appeared on NXT and NXT UK.

The event received generally negative reviews by critics, with the main event being particularly criticised. It later won the Wrestling Observer Newsletter Award for Worst Major Wrestling Show of 2019.
