The men's 200 metre butterfly event at the 2000 Summer Olympics took place on 18–19 September at the Sydney International Aquatic Centre in Sydney, Australia. U.S. swimmer Tom Malchow shattered his own Olympic record to claim a gold medal in the event. Coming from third place on the final turn, he held off a challenge from fast-pacing Denys Sylantyev of Ukraine to touch the wall first in 1:55.35. Sylantyev trailed behind by almost half a second (0.50) to take a silver in 1:55.76, while Australia's Justin Norris settled for the bronze in an Oceanian record of 1:56.17.
