In 2018, Cher returned to film for the romantic musical comedy film Mamma Mia!
Here We Go Again.
New York magazine's Viviana Olen and Matt Harkins commented that "it's only at the climax of the movie when its true promise is fulfilled: Cher arrives ... It becomes clear that every single movie—no matter how flawless—would be infinitely better if it included Cher."
She stars as Ruby Sheridan, who is the grandmother of Sophie, played by Amanda Seyfried, and the mother of Donna, portrayed by Meryl Streep.
Cher recorded two ABBA songs for the film's soundtrack: "Fernando" and "Super Trouper".
Björn Ulvaeus of ABBA commented, "She makes Fernando her own.
It's her song now."

On March 4, 2018, Cher headlined the 40th Sydney Gay and Lesbian Mardi Gras.
Tickets sold out within three hours after she hinted her performance on her Twitter account.
In September 2018, Cher embarked on the Here We Go Again Tour, which is set to finish on December 5, 2020.

While promoting Mamma Mia!
Here We Go Again, Cher confirmed she was working on an album that would feature cover versions of songs from ABBA.
The album, Dancing Queen, was released on September 28, 2018.
Brittany Spanos from Rolling Stone commented that "the 72-year-old makes ABBA songs not only sound like they should've been written for her in the first place but like they firmly belong in 2018".
Marc Snetiker from Entertainment Weekly called it Cher's "most significant release since 1998's Believe" and noted that "the album ender, 'One of Us', is frankly one of Cher's best recordings in years."
Dancing Queen debuted at number three on the Billboard 200, tying with 2013's Closer to the Truth for Cher's highest-charting solo album in the US.
With first-week sales of 153,000 units, it earned the year's biggest sales week for a pop album by a female artist, as well as Cher's largest sales week since 1991.
Dancing Queen also topped Billboard's Top Album Sales chart, making it Cher's first number-one album on that chart.

The Cher Show, a jukebox musical based on Cher's life and music, officially premiered at the Oriental Theatre in Chicago, on June 28, 2018, and played through July 15.
It began Broadway previews November 5, with its official opening on December 3, 2018.
Written by Rick Elice, it features three actresses playing Cher during different stages of her life.
On December 2, 2018, Cher received a Kennedy Center Honors prize, the annual Washington distinction for artists who have made extraordinary contributions to culture.
The ceremony featured tribute performances by Cyndi Lauper, Little Big Town and Adam Lambert.

During 2018, Cher used Twitter to announce she was working on four new projects for the next two years: a Christmas album; a second album of ABBA covers; an autobiography; and a biographical film about her life.

In October 2019, Cher launched a new perfume, Cher Eau de Couture, which was four years in the making.
Described as "genderless", it is Cher's second fragrance after 1987's Uninhibited.
On February 4, 2020, Cher was announced as the new face of fashion brand Dsquared2.
She starred in the brand's spring/summer advertising campaign, which was directed by photographers Mert and Marcus.
In May 2020, Cher released her first Spanish-language song, a cover of ABBA's "Chiquitita".
Proceeds from the single were donated to UNICEF following the COVID-19 pandemic.
