Anti (stylized in all caps) is the eighth studio album by Rihanna, released on 28 January 2016 by Roc Nation and Westbury Road. Rihanna started recording in 2014 after ending her contract with Def Jam Recordings, who had released all of her albums since her debut in 2005. As executive producer, Rihanna recorded Anti with producers including Jeff Bhasker, Boi-1da, DJ Mustard, Hit-Boy, Brian Kennedy, Timbaland and No I.D., at studios in Canada, the United States and France. SZA and Drake contribute guest vocals.

Conceived when Rihanna was experiencing creative struggles and emotional turmoil, Anti features an atmospheric production brought by lo-fi beats, distorted vocals and downtempo arrangements. The first half consists of bass- heavy tracks, and the second is characterised by textured minimalism. Compared to the radio-friendly dance tunes of her previous albums, Anti is more muted and soulful. The album primarily incorporates alternative R&B, pop and dancehall, and it explores eclectic styles spanning hip hop, soul, industrial, psychedelic, doo-wop, country, synth-rock and trap. The lyrics are about the emotions ensued from love and relationships, from endearment and desire to betrayal and liberation, with references to sex, drugs and alcohol.

The promotional campaign for Anti from summer 2014 comprised prolonged release delays and a $25 million deal with Samsung. Rihanna announced the cover art and title at the MAMA Gallery on 7 October 2015. The Anti World Tour ran from March to November 2016, and four songs were released as singles, including the US Billboard Hot 100 number one "Work". In the United States, Anti is Rihanna's second number-one album and the first album by a black woman to spend 300 weeks on the Billboard 200; it was certified six-times platinum by the Recording Industry Association of America (RIAA). The album topped charts in Canada and Norway, and it received multi-platinum certifications in Belgium, Canada, Denmark, France, New Zealand, and Poland.

In contemporary publications, critics commended the album's emotional honesty but were divided on the production, praise centering on Rihanna's newfound musical freedom and criticism on the unfocused track list. Some took issue with the lack of radio-friendly songs, but others noted the musical shift marked Rihanna's artistic maturity as an album artist beyond her status as a pop star. At the 2017 Grammy Awards, the album and its singles received six nominations, including one for Best Urban Contemporary Album. Anti featured on 2010s decade-end lists by such publications as Billboard , NME and Pitchfork. It ranked 230th on Rolling Stone 's 2020 edition of the 500 Greatest Albums of All Time. As of 2023, Anti is the fourth-longest charting female album in Billboard 200 history.
