Love Sux is the seventh studio album by Canadian singer-songwriter Avril Lavigne, released on February 25, 2022, by DTA and distributed by Elektra Records, as her only album on those labels. Musically, it embraces emo pop angst and Lavigne's early skate punk influences from Blink-182, Green Day, NOFX and the Offspring. The album features collaborations with Machine Gun Kelly, Blackbear and Mark Hoppus of Blink-182.

Preceded by the singles "Bite Me" and "Love It When You Hate Me", Love Sux received generally positive reviews from music critics, who praised Lavigne's attitude and noted it as a return to form for the singer. It debuted at number nine on US Billboard 200 with 30,000 equivalent-album units, of which 19,000 were pure album sales. It also entered the top ten in Australia, Germany, Canada, Japan, and the United Kingdom, among many others. Lavigne promoted Love Sux through a series of public appearances and televised performances. The album was nominated for Album of the Year at the Juno Awards of 2023.

A deluxe edition of the album was released on November 25, 2022, following the release of the single "I'm a Mess", a collaboration with British singer Yungblud. Love Sux won the Japan Gold Disc Award of Best 3 Albums.

Following the release of her previous studio album Head Above Water (2019), Lavigne mentioned in a May 2020 interview with American Songwriter magazine that she would like to release some music in 2021 and that she had started working on new material. At the time, Lavigne was without a record label or management team. She began working on new music, collaborating with American musician Travis Barker. The pair produced their first song, "F.U.", in November 2020. The same month, American musician Mod Sun, on whose single "Flames" Lavigne featured in January 2021, introduced Lavigne to producer John Feldmann, who stated "my experience with Avril was unbelievable" adding that "her voice is incredible — her pitch, her tone."

In December 2020, Lavigne confirmed she was recording new music with Feldmann, Barker, Mod Sun, and Machine Gun Kelly. Recording for the album was reportedly completed by February 2021, and on November 3, 2021, Lavigne announced that she had signed with Barker's label, DTA Records. On January 13, 2022, Lavigne revealed the title of her seventh studio album, along with the release date of February 25, 2022.

Four of the tracks of Love Sux are vocal collaborations with other artists, namely Machine Gun Kelly, Blackbear, Mark Hoppus and Yungblud; this is the largest amount of collaborations Lavigne had ever included on an album. On working with Hoppus, Lavigne said "...he blew me away... He was writing in front of me, recording his vocals, playing his bass. He can engineer and he's obviously an awesome songwriter and I got to see that firsthand. I have so much respect for him that I just keep gushing about him."

Love Sux was described by Lavigne in an interview with Entertainment Weekly as the "most alternative record I've made from front to back", further explaining "most of my albums have like pop songs, ballads, and it's quite diverse. The people I worked with really understood me and come from that genre of music". She described the recording of the album as feeling as though she was "back in high school hanging out with the type of people [she] grew up with, and it was just effortless." In an interview with Nylon, Lavigne said that "the album is light and happy, even though there's songs about heartbreak and breaking up" but that "it's also anthemic, and it's powerful, and it has a positive message for people to stand up for yourself, to have self-worth." She further stated that Love Sux is the album she had "wanted to make for [her] whole career," drawing skate punk influences from NOFX, Blink-182, Green Day and the Offspring.

The album has been described by critics as being pop-punk, skate-punk, alternative rock and emo.
