The 70-year-old US pop singer unveiled plans for her first major tour in a decade as she visits 23 cities from October to December, starting in Montreal and finishing in Chicago.
The run of shows has been billed as The Girls Just Wanna Have Fun Farewell Tour, taking its name from her 1983 hit single.

Lauper is releasing a new documentary, Let The Canary Sing, which has been directed by Alison Ellwood and will launch on US TV via Paramount+.
The career-spanning film will premiere the same day the singer is expected at a handprint ceremony at Hollywood's TCL Chinese Theatre.
News of Lauper's last tour comes after she signed a deal with Swedish virtual avatar company Pophouse Entertainment Group, which is behind the ABBA Voyage arena show.
The firm, founded by ABBA's Bjorn Ulvaeus, owns the majority share of Lauper's master recording revenue and publishing.
The company will pursue "creative activations" of her catalogue, including tracks like True Colours and Time After TIme, with live shows, TV plans and other projects.
Announcing the deal, Lauper said: "Since we first met, Pophouse has impressed me with their commitment to maintaining and developing my professional life's work and ensuring its legacy.
"Their creativity and vision, combined with my continued involvement via our unique joint venture, is what is most exciting to me."
She also told Ulvaeus she was inspired by ABBA's Voyage show.
"When I saw the ABBA Voyage, I started to think about what could be done, and then I got excited. I'm not selling, I'm buying."
