Blink-182 is the self titled or untitled last album, by the band of the same name and their last full-length record before an ongoing hiatus. Recorded under the working title of Use Your Erection I & II (a pun of Guns N' Roses' Use Your Illusion albums), the album was released through Geffen Records on November 18, 2003. The album includes guest vocals by The Cure's Robert Smith on the track "All of This".

At almost 50 minutes long, it is Blink-182's longest studio album. It features four hits; Down, Always, Feeling This, and charting at #1, I Miss You. It is said that this album represents a more "mature" Blink than been having seen in the past, such as not having the album contain any toilet humor or joke songs. It was somewhat of a departure from their previous musical atmosphere, the album was described as a "self-meditation on romantic decay." Mark Hoppus, the bassist for the band said in an interview with MTV Album Launch, that the desired effect of the album was for people to listen to it and say "Wait a minute...that's Blink-182?" The band infused experimentalist elements into their usual pop punk sound, inspired by lifestyle changes (Mark, Tom and Travis all became fathers before the album was released) and side-projects (Box Car Racer and Transplants).

Despite having very high airplay from radio and music video channels, the album sold 313,000 copies in its first week debuting #3 on the charts in the United States, which was less than their previous album Take off Your Pants and Jacket, which sold more than 350,000 copies in its first week and topped the charts. Although some criticized the change in musical atmosphere, the album was met with a positive reception from both critics and fans. Most notably Rolling Stone magazine, which gave it 4 out of 5 stars and an average user rating of 4 1/2 out of 5 stars.
