These are the official results of the Women's 400 metres hurdles at the 1992 Summer Olympics in Barcelona, Spain.

[1] The main contenders for the gold medal in Barcelona were the American Sandra Farmer-Patrick, the Soviet World champion Tatyana Ledovskaya and Great Britain's Sally Gunnell.

Ledovskaya, who had so narrowly lost the gold to Debbie Flintoff-King at the 1988 Seoul Olympics, won the gold medal at the 1991 World Championships in Tokyo in 53.11 seconds, with Gunnell winning silver in 53.16.

Farmer-Patrick, who was fourth in the Tokyo final and whose personal best of 53.37 dated back to 1989, ran the fastest pre-Olympic time of the 1992 season, when winning the US Olympic trials in June in 53.62 secs.

Gunnell's superior technique and better stride pattern saw her move clear in the home straight and she went on to win by three metres in 53.23 secs, the fastest time in the world for 1992.
