List of Katy Perry live performances

American singer Katy Perry (also known as Katy Hudson) has released six studio albums, an acoustic album and two live albums since her debut in 2001, spawning four international concert tours as well as numerous televised promotional performances and award show appearances. Her self-titled debut album, Katy Hudson (2001), was strictly Christian pop and contemporary worship music. Since officially adopting the stage name Katy Perry, she has taken on a broader, more “pop” aesthetic and sound, no longer only recording Christian music. Since the release of her sophomore record, One of the Boys (2008), she has been promoting all of her pop records via touring and performances at international shows and festivals, including Jingle Ball and the MTV Video Music Awards, among others.

In 2009, Perry embarked on her first headlining concert tour, the Hello Katy Tour, which visited North America, Europe, Asia and Oceania, grossing just over $1.5 million from 89 shows. Perry released her first EP/live album, MTV Unplugged, as part of the MTV Unplugged series, in November of that year. In 2011, she embarked on her second world tour, the California Dreams Tour, to promote her third studio album, Teenage Dream (2010). The tour visited Europe, Oceania, Asia, North America and marked Perry’s first visit to South America. The tour was an international success, with tickets selling-out, and the show ranking 16th in Pollstar's "2011 Top 25 Worldwide Tours", earning over $59.5 million. At the end of 2011, Billboard Magazine ranked the tour at #13 on its list of "Top 25 Tours" for 2011, earning nearly $48.9 million and won the Favorite Headliner Tour Award at the 38th People's Choice Awards. In July 2012, she released her first documentary theatre movie, Katy Perry: Part of Me, which included footage from the California Dreams Tour.

Perry's third world tour, the Prismatic World Tour, began in May 2014 and ended in October 2015, after having visited Europe, North America, Oceania, Asia and South America. The tour supported her fourth studio album, Prism, which was released in October 2013. The tour grossed more than $204.3 million from 151 shows, with a total attendance of 1,984,503 people between 2014 and 2015, becoming Perry's longest, most-attended, highest-grossing and most successful tour, to-date. The Sydney, Australia concert on 28 November 2014 was recorded for her second live album, The Prismatic World Tour Live, which was released in October 2015, two weeks after the tour ended in San José, Costa Rica.

In July 2016, the singer released "Rise", the official song for the 2016 Summer Olympics. A year later, she released her fifth studio album, Witness (2017); the album’s homonymous track was leaked online in May of 2016. The album was released in June of 2017. To accompany the album's release, the singer broadcast herself for four days on YouTube, with a four-day live-stream, titled “Katy Perry Live: Witness World Wide”. Three months later, Witness: The Tour began in Montréal, Québec, after some dates were either cancelled or rescheduled "due to production issues". At the end of 2017, the tour placed at number 77 on Pollstar's "2017 Year-End Top 100 Worldwide Tours" list, estimating that it grossed $28.1 million and that 266,300 people attended throughout the year. In July 2018, Pollstar ranked the tour on #14 at the Mid Year Top 100 Worldwide Tours 2018 with $48.8 million and 577,617 of tickets sold in 54 shows. The tour grossed more than $124.2 million and it became Perry's second most successful tour to date.

In May 2021, Perry announced her first Las Vegas residency, Play, at the Theatre at Resorts World Las Vegas, with shows scheduled from December 29, 2021 to January 15, 2022. Eight more shows were added later that month in-response to popular demand, extending the residency to March 19, 2022. The Las Vegas residency opened to a sold-out crowd at the 5,000-capacity theatre, with the farthest back seat being only 150 feet from the stage. The singer later announced, in January 2022, that she had added 16 more shows from May 27-August 13, 2022. She then scheduled eight further in October 2022, due to high demand. Play ended on 4 November 2023.
