The Kiss 40th Anniversary World Tour was a concert tour by American rock band Kiss. Def Leppard joined Kiss for the first 42 shows of the tour. Kobra and the Lotus and The Dead Daisies were the opening acts.

​

In the tour program for Kiss' final tour, Simmons reflected on the tour:

With this lineup of Kiss, Eric Singer, Tommy Thayer, Paul Stanley and myself, we have played to the largest South American, European and Australian shows we have ever played at, literally stadiums full of fans showed up en masse. Everyone was there to celebrate Kiss today, here and now. The band are alive and well and I think we're playing better than we ever have. What we've got is four people who believe in the same thing, the notion that we're damn lucky to be up on that stage. Once you feel the same thing in your heart you feel like a team.
