Saturn is the second studio album by British singer-songwriter Nao, released on 26 October 2018 through Little Tokyo Recordings and RCA Records. It was supported by the singles "Another Lifetime" and "Make It Out Alive". "If You Ever" was also released prior to the album in a version featuring American singer 6lack, but he does not feature on the album version. Nao will tour in support of the album across late 2018 and early 2019. The album also earned a Grammy nomination for Best Urban Contemporary Album at the 62nd Annual Grammy Awards
Nao named the album after being told by her friends about the astrological concept of Saturn return, when the planet Saturn returns to the same place in the sky that it was when a person was born. This typically takes 29 years, but the reported "influence" can begin at the age of 27. Nao said: "It's like waking up and coming of age, like: 'I've been going through my twenties and what have I been doing in this relationship?' What have I been doing in this job?' You start to rethink everything – old stuff that your parents taught you or ideas that you believed in. It's like a complete shedding of skin and it can be painful."
On review aggregator Metacritic, Saturn has received a score of 84 out of 100 based on reviews from 12 critics, indicating "universal acclaim". Kyann-Sian Williams of NME rated the album four out of five stars and said that Nao's "honest, cinematic exploration of love, lust, and hardship makes for a compelling adventure – and one you'll happily join [her] on". Williams concluded the review by saying that "Saturn is full of beautiful, intricately unique songs that could never be imitated. Like her, it's simply one of a kind." Writing for The Guardian, Natty Kasambala said that on the album, "although [Nao's] sugary vocals have remained intact, her artistic and personal growth is evident". Kasambala further judged that "It's hard to distinguish any obvious commercial hits. Saturn falls somewhere between the dance hits of producer DJs with big-name features, and earnest, heart-tugging balladry." Kasmbala acknowledged that along with the "rise of R&B classicists" like Jorja Smith, Ella Mai and Mahalia, "Nao presents a compelling alternative to the mainstream".
