The Butterfly Returns was a concert residency by American singer-songwriter Mariah Carey at Caesars Palace in Las Vegas. It began on July 5, 2018 and concluded on February 29, 2020. This was Carey's second concert residency placed in Las Vegas since #1 to Infinity (2015–17).

Carey announced the residency on April 30, 2018 on Twitter, marking her fourth concert residency. The show's set list was arranged by Carey, according to fans' demands on Twitter and polls. This set list differed from the one of her previous residency, #1 to Infinity, as it included lesser-known songs by the singer that did not reach number-one on the Billboard Hot 100. For shows in 2018, the set list consisted of eighteen songs, including duets with frequent collaborators Daniel Moore and Trey Lorenz, with the 2019 leg seeing slight changes to the set. During the residency, Carey completed two concert tours and another residency. She returned to Vegas in February 2020, with a new set list, featuring a "Car Ride" medley, consisting of eight songs, and new tracks from her fifteenth studio album, Caution.

The following set list is obtained from the July 5, 2018 concert.
