The 2015 Aviva Women's Tour was the second staging of The Women's Tour, a women's stage race held in the United Kingdom. It ran from 17 to 21 June 2015 and had a UCI rating of 2.1. As in 2014, the race consisted of 5 stages and ran through southern and eastern England. The defending champion, Marianne Vos, was unable to participate due to injury. The winner of the first stage, Lizzie Armitstead, was unable to participate further in the race after she crashed crossing the finishing line, sustaining a sprained wrist and heavy bruising. Lisa Brennauer assumed the race lead after Armitstead's withdrawal, and after briefly losing the lead to Christine Majerus on stage three, her stage win on the fourth stage allowed her to reassume the race lead which she held to the end of the race.
