The women's 200 metres at the 2009 World Championships in Athletics was held at the Olympic Stadium on 19, 20 and 21 August.
Olympic silver medalist and defending World champion Allyson Felix (USA) established herself as the pre-race favorite, having run under 22 seconds earlier in the season.
Double Olympic champion Veronica Campbell-Brown (JAM) suffered a toe injury and entered Berlin below her peak form.
In the final, Campbell-Brown and Allyson Felix both went out of the blocks quickly and entered the home straight even with one another.
Felix, however, was able to hold her form as Campbell-Brown faltered, crossing the line in 22.02 seconds to win her third World 200m title.
