The Blink-182 and Lil Wayne Tour was a co-headlining concert tour by American rock band Blink-182 and American rapper Lil Wayne. The tour was in support of the group's ninth studio album, Nine, as well as Wayne's previously released twelfth studio album, Tha Carter V (2018). The tour began on June 29 in Hartford, Connecticut and concluded on September 16, 2019, in Cincinnati, Ohio. One date coincided with Blink-182's appearance on the Vans Warped Tour 25th anniversary reunion show, as well as at 2019's Riot Fest. Welsh punk group Neck Deep was the opening act on the tour. It was the band's last tour with guitarist/vocalist Matt Skiba before his departure in 2022 upon original member Tom DeLonge's return.
To promote and announce the tour, Blink-182 and Lil Wayne released live and studio mashups of their songs "What's My Age Again?" and "A Milli".[1][2] One month after first publicizing the tour, Blink-182 also announced they would perform their 1999 album Enema of the State in full at all shows, in addition to their hit singles and new music.[3]
