The Stadium Tour was a co-headlining concert tour by British rock band Def Leppard and American rock band Mötley Crüe, taking place in the summer and fall of 2022 in venues across North America. Poison and Joan Jett & the Blackhearts served as the tour's special guests, while Classless Act was the opening band. It was Mötley Crüe's first major tour in seven years (following their final world tour in 2014–2015), and Def Leppard's first in three years, with the latter touring in support of their twelfth studio album Diamond Star Halos.
