The Party Tour was the debut concert tour by American recording artist, Pink. The tour supported her second studio album Missundaztood (2001).

While promoting her second studio album, Missundaztood, Pink stated she was proud of the "new" sound of the record and was ready to go on the road with her new band. Planning the tour, Pink was given complete control of all aspects of the tour including staging and opening acts. During an interview at the ESPY Awards, Pink mentioned she chose the group "Candy Ass" because she'd always wanted to be in an all-female band. She further stated that she would cover songs by her musical inspirations including 4 Non Blondes, Aerosmith, Janis Joplin, Guns N' Roses and Mary J. Blige.

The stage was very simplistic consisting of a backdrop resembling a brick wall with a graffiti text saying "P!nk", a video screen, lights, instruments, and one microphone. The show's setup was designed for the nightclubs and concert halls Pink would play that had an average audience size of 3,000 attendees. During this time, Pink's peers Britney Spears and Christina Aguilera were touring the U.S. as well in sports arenas and amphitheaters. Pink (who previously condemned the comparisons) stated:

"Big productions, to me, are great—like, I love going to Vegas and seeing shows—but I think that sometimes it's distracting, especially when you are there to listen to the music. I remember being on tour with 'NSYNC, and I don't know if this is appropriate, but it was something like a $5 million stage, and to me, that was just like, 'Man, I will take a box out there and stand on it with a microphone. I ain't spending that much money.' I love the shows that are in dingy little dark clubs, smoky, no production whatsoever. My stage show is raw and unpredictable. It's not a lot of choreography this time. There's practically no sequencing involved whatsoever. It's just instruments and a voice and incredible music. When there is a lot of sequencing or ProTools or DATs involved, it gets a little strange, so this is going to be definitely more organic."

During rehearsals, Pink contacted Lenny Kravitz and jokingly stated she was rehearsing to be the opening act on his upcoming North American tour. She invited the rock singer to watch her rehearse. She also sent him a pair of black and pink panties with "The P!nk/Lenny Tour" written on them. Upon the completion of her North America dates, Pink continued to tour the United States as the opening act for the "Lenny Live Tour". Once her outing with Kravitz was complete, the singer set out on a mini-tour of Europe, visiting England, Ireland and Germany. She continued her tour into Japan and New Zealand before touring Australia with the "Rumba Festival".

The tour was sponsored by Bally Total Fitness, giving the tour the sponsored name, "Bally Total Fitness presents Pink's 'The Party Tour 2002'". In conjunction with the sponsorship, the fitness center launched the "Get Your Body Started" movement classes in over 400 Ballys throughout the US and Canada. The centers also hosted dance competitions set to Missundaztood.
