Thank U, Next is the fifth studio album by American singer Ariana Grande. It was released on February 8, 2019, by Republic Records, six months after her fourth studio album Sweetener (2018), which was conceived in the midst of Grande's personal struggles, including the death of ex-boyfriend Mac Miller and the end of her engagement to Pete Davidson.

Grande began working on the album in October 2018, enlisting writers and producers such as Tommy Brown, Max Martin, Ilya Salmanzadeh and Pop Wansel. With Thank U, Next, Grande did not utilise the traditional promotion cycle that she employed for her previous album releases. Musically, the album is predominantly pop, R&B and trap. It was described as Grande's most personal record up to that point, with its lyrical content reflecting on personal flaws, grief and denial, as well as independence and self-empowerment.

The album was preceded by two singles: the title track and "7 Rings", both of which debuted atop the Billboard Hot 100 chart, becoming Grande's first two number-one songs in the United States. "Break Up with Your Girlfriend, I'm Bored" became the third single on the day of the album's release, peaking at number two on the Hot 100. All of the album's 12 tracks entered the Hot 100, with the singles occupying the top three spots, making Grande the first soloist to achieve this feat. The album topped the charts in 17 countries, and broke many streaming records upon release, including the records for the largest weekly streams for a pop album and a female album in the United States. It was certified double platinum by the Recording Industry Association of America, and landed at number two on the US Billboard 200 Year-End chart of 2019. Globally, it was the eighth best-selling album of 2019, and fourth best-selling album by a female artist.

Upon its release, Thank U, Next received critical acclaim, with praise on its cohesiveness, the production and Grande's vulnerability throughout the record. In support of both Sweetener and Thank U, Next, Grande embarked on the Sweetener World Tour from March to December 2019. The concert tour was commercially successful, grossing over $146 million from 97 shows.

Named by several publications as the best album of 2019, it was included in numerous publications' year-end and decade-end lists. Thank U, Next and its songs received nominations for four Grammy Awards, an American Music Award, a Billboard Music Award and a Juno Award.
