The women's marathon was one of the road events at the 2017 World Championships in Athletics in London. It took place on 6 August 2017 on the streets of London, and consisted of four laps of a roughly 10-kilometre (6.2 mi) course which passed several of London's landmarks. For the first time in World Championships history, the men's and women's marathons took place on the same day. The race was won by Rose Chelimo of Bahrain in 2:27:11, seven seconds ahead of Kenya's Edna Kiplagat in second. Amy Cragg of the United States finished in third, separated from Kiplagat by less than a second.
