The Junkie Tour is the second concert tour by Canadian American recording artist, Alanis Morissette. The tour promoted her fourth studio album, Supposed Former Infatuation Junkie.

Morissette took a break in the tour to co-headline a North American tour with American recording artist, Tori Amos. The tour was known as the 5 ½ Weeks Tour. The tour was extended into places she had never toured in 2000, where it became known as the One Tour.
