The women's 100 metres at the 2013 World Championships in Athletics was held at the Luzhniki Stadium on 11–12 August and was won by 0.22 seconds by Shelly-Ann Fraser-Pryce.

[1] As of 2024, this is the greatest winning margin in the women's 100 metres at these championships and the only time this event has been won by two-tenths of a second.

The semis were faster, since although the first was slowest at 11.08, the other two were won in under 11 seconds, with the fastest time qualifier Alexandria Anderson at 11.01.

In the final, there was no doubt who would win as Shelly-Ann Fraser-Pryce shot out of the block leaving nothing but a pink streak (hair and shoes) for her competitors to follow.

[2] Slow reacting Kerron Stewart gave up .06 at the start line but lost the silver medal by only .04.
