The individual dressage event, part of the equestrian program at the 2004 Summer Olympics, was held from 19 to 25 August 2004 at the Olympic Equestrian Centre on the outskirts of Markópoulo, in the Attica region of Greece.
Like all other equestrian events, the dressage competition was mixed gender, with both male and female athletes competing in the same division.
The final round of dressage competition was the Grand Prix Freestyle Test.
Fifteen pairs competed in this round, in which they designed their own program of movements set to music.
They were judged on both execution of the movements (technical) and how well their performance matched the music (artistic).
