What was the title of Beyoncé’s first concert tour as a solo headliner?

Beyoncé’s first concert tour as a solo headliner was the Dangerously in Love Tour.

The tour supported her debut solo album, Dangerously in Love, and took place in Europe in late 2003. It followed the album’s release and presented Beyoncé as a solo live act after years of performing with Destiny’s Child. The set combined her new solo songs with material associated with her earlier group career.

The tour began in Manchester, England, on November 3, 2003, and concluded in London on November 19, 2003. It was a relatively short European tour rather than one of Beyoncé’s later worldwide arena productions.

Later tours had more widely recognized titles, including The Beyoncé Experience, I Am... World Tour, and The Mrs. Carter Show World Tour. Those names can cause confusion, but the Dangerously in Love Tour came first and specifically supported Beyoncé’s debut solo album.
