The men's 100 metre butterfly event at the 2012 Summer Olympics took place on 2–3 August at the London Aquatics Centre in London, United Kingdom.

Rallying from seventh at the halfway turn, Michael Phelps claimed his seventeenth gold and twenty-first career medal in 51.21, achieving a second Olympic three-peat. Trailing behind Phelps by 0.23 seconds, South Africa's Chad le Clos and Russia's Yevgeny Korotyshkin tied for the silver in a matching time of 51.44.

Leading early at the turn, Serbia's Milorad Čavić, who famously lost to Phelps in Beijing four years earlier by a fingertip, faded down the stretch to match Germany's Steffen Deibler with a fourth-place time in 51.81. Netherlands' Joeri Verlinden (51.82), U.S. swimmer Tyler McGill (51.88), and Poland's Konrad Czerniak (52.05) also vied for an Olympic medal to round out a historic finish.

Austria's Dinko Jukic (51.99), fourth-place finalist in the 200 m butterfly few days earlier; and Kenya's Jason Dunford (52.16), fifth in Beijing, missed the final roster after placing ninth and sixteenth respectively in the semifinals. Other notable swimmers featured Japan's Takeshi Matsuda, who elected not to do a swimoff with Germany's Benjamin Starke (a matching time of 52.36) on the morning prelims; his teammate Takuro Fujii (52.49) and Papua New Guinea's Ryan Pini (52.68), both of whom finished sixth and eighth in Beijing; and Sweden's 2000 champion Lars Frölander, who posted a twentieth-place time of 52.47 in his sixth Olympics.
