Swimming at the 2000 Summer Olympics – Men's 200 metre individual medley

The men's 200 metre individual medley event at the 2000 Summer Olympics took place on 20–21 September at the Sydney International Aquatic Centre in Sydney, Australia.

Massimiliano Rosolino blasted a new Olympic record to add Italy's third gold medal in swimming at these Games. He edged out U.S. swimmer Tom Dolan with a fastest split (33.52) on the breaststroke leg to take over the lead at the final turn, and hit the wall first in a sterling time of 1:58.98, clipping 0.93 seconds off a record set by Hungary's Attila Czene in Atlanta. Dolan, the defending champion in the 400 m individual medley four days earlier, became the first American to break a two-minute barrier, taking home the silver in a new national record of 1:59.77. Meanwhile, Tom Wilkens earned a bronze in 2:00.87, handing an entire medal haul for the U.S. team with a two–three finish.

Czene, the defending Olympic champion, finished outside the podium in fourth place with a time of 2:01.16. Netherlands' Marcel Wouda came up with a spectacular swim on the breaststroke leg, but fell short to fifth spot in 2:01.48. Wouda was followed in sixth by Germany's Christian Keller (2:02.02), and in seventh by France's Xavier Marchand (2:02.23). Finland's world record holder Jani Sievinen closed out the field with an eighth-place finish in 2:02.49.
