Neighborhoods is the sixth studio album by American rock band Blink-182, released September 27, 2011, through DGC Records and Interscope. Their first album of new material in eight years, its recording followed the band's breakup and later reconciliation. Due to conflicts within the trio, the band entered an "indefinite hiatus" in 2005 and the members explored various side-projects. After two separate tragedies regarding the band and their entourage, the members of Blink-182 decided to reunite in late 2008, with plans for a new album and tour. It was the last studio album to feature founding member Tom DeLonge until his return on 2023's One More Time....

The band's studio autonomy, tours, managers, and personal projects stalled the recording process, which lasted from shortly after the band's February 2009 reunion to July 2011. Blink-182 developed Neighborhoods in separate studios and regrouped at various periods to record. Their numerous delays in the recording process resulted in the cancelation of a European tour and label executives setting a deadline for the album to be due. The trio wrote lyrics on such subjects as isolation, confusion, and death. They infused inspiration from each member's various musical tastes to form a unique sound that recalled their separate upbringings, leading the trio to compare the album to separate neighborhoods.

Neighborhoods was released to mixed reviews from critics; some felt it was a natural evolution from the band's previous releases, while others found it stale and disjointed. The album debuted at number two on the Billboard 200 and "Up All Night" and "After Midnight" were released as singles, with both attracting modest success on Billboard's Alternative Songs chart. Despite this, Neighborhoods did not sell as well as earlier releases and the band would depart from Interscope the following fall.
