Endless Summer Vacation is the eighth studio album by American singer Miley Cyrus, released on March 10, 2023, via Columbia Records. It is her first new body of work since leaving RCA Records after her seventh studio album Plastic Hearts (2020) and signing with Columbia in early 2021. A pop and dance-pop record, Endless Summer Vacation is a shift from the synth-pop, rock, and glam rock genres featured on Plastic Hearts. Cyrus related its overall concept to her affection for Los Angeles, where the album was mainly recorded, and its track sequencing to the course of a day. Brandi Carlile and Sia are featured as guest vocalists.
 The album was supported by three singles. The lead single, "Flowers", set several streaming and chart records and spent eight weeks atop the U.S. Billboard Hot 100, marking Cyrus's second number-one in the country, and topped the charts in 36 other countries. "River" and "Jaded" followed as subsequent singles in March and April 2023.
 Upon release, Endless Summer Vacation received positive reviews from music critics, who complimented its production, commercial appeal, and Cyrus's vocal performance. Commercially, it reached number-one in ten countries and the top 10 in 17 countries. The album has been nominated for Album of the Year and Best Pop Vocal Album at the upcoming 66th Annual Grammy Awards, whilst "Flowers" received nominations for Record of the Year, Song of the Year and Best Pop Solo Performance.
 A digital edition of the album featuring the song "Used to Be Young" was released on August 25, 2023. With its release, Endless Summer Vacation became Cyrus's first album to feature multiple US top-ten singles since Bangerz (2013). She performed eight of the twelve tracks for the Disney+ documentary concert special Endless Summer Vacation (Backyard Sessions), which was released on March 10, 2023. An updated version of the special was broadcast on ABC on August 24, 2023 and released on Hulu the day after.
 After ending her eight-year contract with RCA Records, Cyrus signed with Columbia Records in March 2021. Her first releases with the label were a remix of the Kid Laroi's "Without You" and the live album Attention: Miley Live, released in April 2021 and April 2022 respectively. In an article published in October 2021, Billboard confirmed that Cyrus was working on her next album. The album was described as "her love letter to LA" that represents the physical and mental growth she experienced during production.
 Cyrus wrote several songs with Michael Pollack and Gregory "Aldae" Hein. They were conceived only with piano, then evolving into their final versions. Pollack said that Cyrus decided to focus on songcraft before tackling the production. She worked with several producers including Kid Harpoon, Tyler Johnson, Greg Kurstin, and Mike Will Made It, the latter of whom contributed to Bangerz (2013), Miley Cyrus & Her Dead Petz (2015), and She Is Coming (2019). The album was recorded in Los Angeles.
 Endless Summer Vacation is a pop and dance-pop record, incorporating rock, country and experimental songs. Cyrus explained that the album is divided into two parts: AM and PM. AM represents "the morning time, where there's a buzz and energy and there's a potential of new possibilities", while PM represents the nighttime, which "feels like there's a slinky, seediness and kind of a grime but a glamour at the same time".
 On December 16, 2022, posters with the caption "New Year, New Miley" were placed in major cities worldwide. Cyrus revealed the album title, cover, and release date on January 5, 2023. The cover was photographed by Brianna Capozzi and "fully executed by [Cyrus] without visual effects", and depicts a blonde Cyrus wearing a black one-piece swimsuit hanging from a helicopter ladder. It was compared to a similar photograph of Madonna for her coffee table book Sex (1992). The album trailer was released the same day, and "reflects the visual world that [Cyrus] has built around this very personal body of work" with a monologue and visuals that reference Los Angeles sights. Limited quantities of postcards featuring the album cover were autographed by Cyrus and offered through her website later that month. On February 27, 2023, Cyrus revealed the album's tracklist.
 Endless Summer Vacation was released on both digital and physical formats on March 10, 2023, through Columbia. Red and clear vinyl copies of the album were made exclusive to Cyrus' website, and white vinyl copies were made exclusive to retailers including Target in the United States, HMV in the United Kingdom, and JB Hi-Fi in Australia.

 The album was met with generally favorable reviews from music critics, becoming Cyrus' most acclaimed album to date. At Metacritic, which assigns a weighted mean rating out of 100 to reviews from mainstream critics, the album received an average score of 79. Rolling Stone's Brittany Spanos called it Cyrus' "sharpest, most independent album yet" and "a powerful artistic statement, focused and clear-eyed as Cyrus seems to have found herself in her thirties". Maura Johnston of the same outlet wrote that the album "feels like a recap of her career's 15-plus years, with Cyrus breezing through genres with the ease of a well-seasoned tourist." Helen Brown of The Independent called it a "lovely long bask in Cyrus's maturing talent." According to Nick Levine of NME, the album "may appear subdued by [Cyrus'] standards, but it remains remarkably intriguing" and "feels like an accurate reflection of who she is as an artist – and a person – in 2023." Emily Swingle of Clash believed that "while previous releases have been Cyrus attempting to don the outfit of another artist she admires, this release feels like she is fully embodying her own skin – this is a release that aims for timelessness in its own right, allowing the true, unfiltered Miley Cyrus to step into the sunlight."
 The Daily Telegraph's Neil McCormick wrote "there is much to be admired in Cyrus's defiant will to keep messing about on pop's more eccentric fringes." Mary Siroky of Consequence called the album "cohesive without feeling repetitive", adding that "that sort of plain-spoken storytelling might have made for a good record; Cyrus' vocals take things further into the territory of greatness." Chris Willman of Variety described it as "a fairly unpretentious pop record that has some stylistic micro-shifts that don't announce themselves too proudly or loudly," noting that it balances "mellow gold and dance-pop." David Smyth of Evening Standard felt that "the strength of Cyrus is suiting her mighty voice to so many styles, on an album where even those with the shortest attention spans should find a new favourite". Alexis Petridis of The Guardian opined Cyrus "has delivered a hazily atmospheric album that plays to her provocative strengths." Heather Phares of AllMusic praised Cyrus's growth both as a vocalist and a songwriter, and wrote, "this is a mature album in the best sense of the word; like a good relationship, it's smooth, but not dull, grounded in resilience and self-love." Vulture's Craig Jenkins opined the album "showcases a more unified and refined version of Miley," feeling that "the sound is pliable and chewy, and the lyrics are unpretentious."
 In a more mixed review, Sal Cinquemani of Slant Magazine complemented Cyrus' vocal performance, but criticized "nondescript lyricism." For David Cobbals of The Line of Best Fit, Endless Summer Vacation "is a good album with each track deserving of a listen, but in the same breath, the majority of them aren't worthy of a replay either." Pitchfork's Shaad D'Souza called it "edgeless and synthetic." Mark Richardson of The Wall Street Journal felt that it "boasts several songs that rank among her best", but criticized its second half, which "reveals the limitations of Ms. Cyrus's small-plate method of construction." Los Angeles Times' Mikael Wood was critical of the album's lyrics, however opining that "[Cyrus'] singing is vivid enough on Endless Summer Vacation to make up for some mushy songwriting." Kyle Denis of Uproxx called it a "perfectly fine record" and "undeniable proof that Miley Cyrus is still capable of playing and thriving in the mainstream pop game," however feeling that it "ultimately suffers from how safe it is."
 Upon its release, Endless Summer Vacation was a commercial success. The album officially debuted at No. 1 in ten countries, and was in the top 5 of seventeen official charts. In the United States, Endless Summer Vacation debuted at number three on the US Billboard 200, earning 119,000 album-equivalent units, including 55,000 pure album sales. It is Cyrus's 14th US top-10 album, and her biggest week by units since Billboard began calculating them in December 2014. In Canada, it debuted at number two on the Canadian Albums Chart.
 In the United Kingdom, on the UK Albums Chart, the album went No. 1, becoming Cyrus' second number one album after 2013's Bangerz.
