The 2018 Super Show-Down was the inaugural Super Show-Down professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held for wrestlers from the promotion's Raw, SmackDown, and 205 Live brand divisions. The event took place on October 6, 2018, at the Melbourne Cricket Ground in Melbourne, Victoria, Australia, and was WWE's first pay-per-view event held in Australia.

Ten matches were contested at the event. In the main event, Triple H defeated The Undertaker in a No Disqualification match that was billed as the "Last Time Ever". In the penultimate match, Daniel Bryan defeated The Miz to earn a match for SmackDown's WWE Championship. In other prominent matches, The Shield (Roman Reigns, Seth Rollins, and Dean Ambrose) defeated Braun Strowman, Dolph Ziggler, and Drew McIntyre, AJ Styles defeated Samoa Joe by submission in a no countout, no disqualification match to retain the WWE Championship, and Buddy Murphy defeated Cedric Alexander to win 205 Live's WWE Cruiserweight Championship.

The event was met with mixed to positive reception from critics. Although the six man tag team match, Cruiserweight Championship, SmackDown Tag Team Championship, and WWE Championship matches were highly praised, the Daniel Bryan vs. The Miz match and the main event were subject to criticism.
