The Pussycat Dolls Tour was the planned third concert tour by American girl group the Pussycat Dolls. It was announced in 2019, when Nicole Scherzinger, Ashley Roberts, Carmit Bachar, Kimberly Wyatt and Jessica Sutta revealed that they were reforming for new music and a brand new concert tour. Former member Melody Thornton declined to reunite but decided to continue with her career as a solo recording artist. The announcement followed the release of "React", the first new song by the group in more than a decade.

The Pussycat Dolls were an American girl group and dance ensemble, founded in Los Angeles, California, by choreographer Robin Antin in 1995 as a burlesque troupe. At the suggestion of Jimmy Iovine, Antin decided to take the burlesque troupe mainstream as a pop group. Antin negotiated a record deal with Interscope Geffen A&M Records in 2003 turning the group into a music franchise comprising Nicole Scherzinger, Carmit Bachar, Ashley Roberts, Jessica Sutta, Melody Thornton, and Kimberly Wyatt. Their debut single, "Sway", was featured on the soundtrack of the 2004 film Shall We Dance?.
