The 20th Anniversary Tour (originally known as the Neighborhoods Tour) is the eleventh headlining concert tour by American rock band, blink-182. It began on August 16, 2011, in Montreal, Quebec and finished on October 11, 2014, in Las Vegas, Nevada. The tour supported the band's sixth studio album, Neighborhoods (2011). Originally planned to begin in Europe, the tour was postponed so the band could focus on finishing their album. The tour visited Canada in 2011, the United States and Europe in 2012, Australia in 2013, and Europe again in 2014. The 20th Anniversary Tour was the last tour with Tom DeLonge, who left the band for the second time in 2015, until his return in 2022.
