Lady Gaga Enigma + Jazz & Piano

Lady Gaga Enigma + Jazz & Piano was a concert residency by American singer-songwriter Lady Gaga held at Dolby Live in the Las Vegas Valley, Nevada. The residency featured two distinct shows: Enigma, a theatrical extravaganza highlighting Gaga's biggest hits, and Jazz & Piano, which included songs from the Great American Songbook as well as stripped-down versions of her own material. Enigma ran from its debut on December 28, 2018, to its finale on December 30, 2019, while Jazz & Piano opened on January 20, 2019, and continued across multiple legs—pausing for a 21-month COVID-19 hiatus—until its final performance on July 6, 2024.

The Enigma show was complimented for its theatricality and Gaga's showmanship, although some reviewers found it disjointed, and deemed the narrative confusing and unnecessary. The Jazz & Piano concerts were critically acclaimed – journalists found them a nostalgic throwback to the "Golden Age" of Las Vegas, and praised Gaga's vocal skills. The combined performance of the two shows made Gaga's the highest grossing Las Vegas Valley concert residency of 2019. By the residency's end, Gaga became the fourth woman to cross the $100 million threshold for a single residency engagement.
