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).
