These are the results of the mixed doubles competition in badminton at the 2008 Summer Olympics in Beijing.

Matches were played using a best-of-three games format.

Games were played to 21 points, using rally scoring.

Each game had to be won by a margin of two points, except when the game was won by a player who reached 30 even if the lead was only 1 at that point.

The top four seeds in the tournament were placed in the bracket so as not to face each other until the semifinals.
