The women's marathon at the 2008 Summer Olympics took place on August 17 around an urban circuit specifically designed for the competition at Beijing, and finished in the Beijing National Stadium; it was, as of today, the last time in Summer Olympics history in which women's marathon route start and/or finish was located in the Olympic Stadium.

The winner was Constantina Diṭă-Tomescu of Romania who at one point took a lead of over a minute and maintained it ahead of the chasing pack all the way into the stadium.

In second place was Catherine Ndereba of Kenya who completed the race in 2:27:06, closely followed by bronze medalist Zhou Chunxiu of China who finished in a time of 2:27:07.

World record holder Paula Radcliffe of Great Britain took part in the race despite injury problems that bothered her throughout the previous year.

However, she did not feature for much of the race and had to pause and do some exercises to rid herself of cramps at one point.
