AFI (also referred to as The Blood Album) is the tenth studio album by American rock band AFI. It was released on January 20, 2017, through Concord Bicycle Music. The album release includes four limited sleeve art and vinyl color variants, corresponding to each of the four members of AFI, and associated with each of the four blood groups (A, AB, B and O).

Hailed by some critics as a comeback album, AFI saw the band experiment into post-punk and new wave sounds, which echoed off of the band's side projects, particularly Blaqk Audio and Dreamcar, which all infused elements of these genres. The album was noted for a strong influence of the band's childhood influences, particularly the likes of Morrissey, Echo and The Bunnymen, The Cure, and Joy Division. The decision to explore this route was both hailed and criticized by contemporary music critics. Some critics felt that this direction marked one of the most ambitious albums by AFI, while others felt it was done as a cautious move to appeal to mainstream audiences.

Commercially, AFI was the band's most successful domestic album since Decemberunderground, debuting at number 5 on the Billboard 200, with 29,000 equivalent music units moved. It was the band's third album to debut in the top five in the Billboard 200, and tied with Sing the Sorrow as the second highest debut album for AFI in the United States. In Australia, AFI debuted at 12 on the ARIA Charts, being their strongest release on the album since Decemberunderground as well. In Canada and the United Kingdom, the album did not sell as well as previous efforts.

After the conclusion of the Burials tour, members of AFI undertook several side projects. Vocalist Davey Havok and guitarist Jade Puget focused on the hardcore band called XTRMST, which released its eponymous debut album in 2014. Havok and Puget also worked on a third studio album with Blaqk Audio which was released in 2016. Finally, in late 2016 Havok worked with members of No Doubt on a new wave supergroup, called Dreamcar. This led to speculation about the band breaking up.

In a June 2016 interview with Aggressive Tendencies, Jade Puget confirmed that AFI had begun working on new material for their tenth studio album, but chose not to reveal more information about it, including the release date. About 60 songs were written for the album.

The album was recorded at Megawatt Recording in the Valley Village neighborhood of Los Angeles, with Jade Puget as the main producer, and Matt Hyde as co-producer. Hyde handled recording, while Marcel Fernandez and Thomas Bellier did additional engineering. Hyde mixed the recordings, before the album was mastered by Tom Baker at Baker Mastering.

The album cover, designed by Frank Maddocks, is dark red and features three stylized blood drops—which are a window to the gatefold. While the album title does not appear on the cover, AFI (The Blood Album) is printed on a sticker on the shrink wrapping. On the album title, Havok states:

I started to recognize the reoccurrence of blood in the lyrics that I was writing for what would eventually become the record. I brought it to Jade's attention early on in the process as something we might want to revisit at the time we decided what was generally gonna comprise the finished record.
