Muhammad Zulfahmi bin Khairuddin (born 20 October 1991) is a Malaysian motorcycle racer.
Born in Banting, Selangor, Malaysia, Zulfahmi made his debut in the 125cc world championship at the 2009 Malaysian Grand Prix where he finished 20th. In 2010, Zulfahmi competed in his first full season on board an Aprilia for the Air Asia-Sepang International Circuit.
Zulfahmi achieved his first pole position by a Malaysian rider in any class at his home race in October 2012. Zulfahmi led for most of the race, but finished second behind team-mate Sandro Cortese, after Cortese made a final-lap pass. At the end of the 2012 MotoGP campaign at Valencia, he claimed the 2nd podium of his career; he climbed from 17th on the grid to finish 3rd behind Danny Kent and Sandro Cortese in a dramatic thrilling race.
Zulfahmi briefly returned to Grand Prix racing but after a poor start to the 2018 season he decided to retire from racing.
