The qualifying standards were 51.55 s (A standard) and 52.35 s (B standard).

Favourites for the event included Sanya Richards-Ross and the reigning world champion, Christine Ohuruogu. In the final, Richards-Ross made a rapid start and quickly took the lead, while Ohuruogu ran a more even-paced race, but was well down the field entering the final straight. However, in the last 100 metres Richard-Ross, clearly tired from her earlier effort, began to tie up badly, while Ohuruogu began to surge through the field. At the line, Great Britain's Christine Ohuruogu won in 49.62 seconds to add the Olympic title to her World title, just pipping Shericka Williams by 0.07 seconds to take gold. Richards-Ross faded to third, and bronze, in 49.93.
