The Blond Ambition World Tour was the third concert tour by American singer-songwriter Madonna. The tour was launched in support of her fourth studio album, Like a Prayer, and the soundtrack, I'm Breathless. The tour reached North America, Europe and Asia. It was a highly controversial tour, mainly for its juxtaposition of Catholic iconography and sexuality.

Rolling Stone called it an "elaborately choreographed, sexually provocative extravaganza" and proclaimed it "the best tour of 1990." In 1991, a documentary film, Truth or Dare (In Bed with Madonna outside North America), was released chronicling the tour. The tour received the "Most Creative Stage Production" at the Pollstar Concert Industry Awards. The tour was named the Greatest Concert of the 1990s by Rolling Stone. In 2015, the BBC credited the tour with "invent[ing] the modern, multi-media pop spectacle".
