Athletics at the 2008 Summer Olympics – Women's 4 × 100 metres relay



The women's 4 × 100 metres relay event at the 2008 Olympic Games took place on 21 and 22 August at the Beijing Olympic Stadium.

There were 16 NOCs competing at this event, selected by the average of the two best marks in the qualifying period. Finland and Cuba qualified but withdrew, and were replaced by Thailand and Nigeria.

Originally, the Russian team won the gold medal but was disqualified in 2016 after Yuliya Chermoshanskaya had her blood and urine samples re-analyzed, and tested positive for two prohibited substances. One of her teammates, Yulia Guschina, was also later sanctioned for doping.
