The Kissworld Tour was a concert tour by the American rock band Kiss.^[1] The tour marked the return of the Creatures of the Night costumes which had previously been seen on the sixth annual Kiss Kruise. The tour began on May 1, 2017, in Moscow, Russia^[2] and concluded in Viveiro, Spain on July 14, 2018.

In the tour program for the band's final tour, both Thayer and Singer reflected on the tour:

The dressing scene before a Kiss show is very serene. Everybody has their own distinctive personalities. I've heard people say that I'm the quiet one and that's probably true. I don't say as much but that's just the way I am and that's how I'm most comfortable. – Tommy Thayer

You've heard people getting ready for a game like a football player how they get themselves amped up. That's kind of what we do. Sometimes people will be very quiet and focus and keep to themselves but most of the time I'm jumping around and acting crazy. – Eric Singer^[3]

Ben Siegel from The Buffalo News described the Niagara Falls concert as "These guys are insane entertainers. They’re intense. They’re flammable. Simmons’s mouth, and that infamously long tongue of his, drip with (stage) blood. They own this genre of hard rock. They invented it."^[4]
