Saïd Aouita (born November 2, 1959) is a former Moroccan athlete, winner of 5000 meters at the 1984 Summer Olympics.

Born in Kenitra, Morocco, Saïd Aouita dominated middle distance running in the 1980s at all distances between 800 meters and 5000 meters.

Aouita's first major international competition was the 1983 World Championships held in Helsinki where he contested the 1500 m. In the final, the pace dawdled for the first 1000 m, tactics that did not suit Aouita, and he was outkicked by the sprinters, finishing third. After this experience, Aouita decided to run 5000 m at the Los Angeles Olympics. The 5000 m final was run at a very fast pace set by Antonio Leitão from Portugal, which suited Aouita much better than the tactics used in Helsinki. He stayed behind Leitão and then sprinted past him on the last lap to win.

In the next season, Aouita ran two world records: at first in 5000 m (13:00.40) and then in 1500 m (3:29.46). In 1986, Aouita was the overall winner of the IAAF Grand Prix series. In 1987, Aouita broke Steve Cram's 2000 m world record with a time of 4:50.81. Only six days later, he broke his own world record for 5000 m, and in the process became the first man to break 13 minutes, finishing in 12:58.39.

For the World Championships held later that year, Aouita had provisionally entered the 800 m, 1500 m, 5000 m and 10 000 m (probably to keep his opponents guessing), but eventually decided just to contest the 5000 m. In the 5000 m final, John Ngugi from Kenya set a fair pace, but by no means fast. Aouita, always in control of the race, made his move just before the bell, leading a mass sprint for the finish that he won in 13:26.44.

Aouita sought new challenges for himself in the Olympic year of 1988. Instead of staying within the comparative security of 5000 m competition, the distance at which he was the reigning Olympic and World champion, he decided to concentrate his efforts on the shorter distances. At the Seoul Olympics he attempted to try the 800 m/1500 m double. Aouita easily won his heat and semi-final in the 800 m, but had his left leg heavily bandaged to protect a recently sprained hamstring. In the 800 m final, a very fast pace was set to try to nullify Aouita's fast finish. Aouita ran according to his race plan, but in the end he was outkicked by the 800 m specialists and finished third. His bronze medal made him the only man in Olympic history to win medals at both the 800 m and 5000 m. However, the race had aggravated his hamstring injury, and although he qualified for the semi-finals of the 1500 m, he withdrew before they started.

In the next year, Aouita won the World Indoor Championships in 3000 m. Later, he ran his last world record, breaking Henry Rono 's record in 3000 m by the time of 7:29.45. Aouita did not compete in the 1990 outdoor season, and when he returned to competition, was unable to recapture the dominance he had imposed during the 1980s. His final appearance at the World Championships, in 1991 at Tokyo, was a barely noticed eleventh in the 1500 m.
