Portals (stylized in all caps) is the third studio album by American singer-songwriter Melanie Martinez. The album was released on March 31, 2023, through Atlantic Records. It is Martinez's first album after she took her usual three-and-a-half-year hiatus from releasing music. After she returned from her hiatus, she rebranded her public persona of usual light pastel colors from her previous albums and EPs, adopting prosthetic makeup and elaborate costumes to resemble a fantasy creature with darker colors with themes of nature. In support of the album, Martinez embarked on the Portals Tour in May 2023.

The album had three singles: "Death", "Void", and "Evil"; the first two marked her first appearances on the chart, respectively reaching numbers 95 and 61 on the Billboard Hot 100. The album debuted at number two on the US Billboard 200 with first-week sales of 142,000 units, becoming her highest-charting album there. The project was set to be Martinez's third visual album, with seven music videos released; however, the idea was scrapped in favour of her upcoming fourth and fifth studio albums.
