Lee Chong Wei is a Malaysian badminton player. As a singles player, Lee was ranked first worldwide for 349 weeks, including a 199-week streak from 21 August 2008 to 14 June 2012. He is the fifth Malaysian player after Foo Kok Keong, Rashid Sidek, Roslin Hashim and Wong Choong Hann to achieve such a ranking (since official rankings were first kept in the 1980s), and is the only Malaysian shuttler who has held the number one ranking for more than a year. On 2 May 2023, Lee was inducted to BWF Badminton Hall of Fame. He is widely regarded as one of the greatest badminton players of all time.
Lee is a triple silver medalist at the Olympic Games, and the sixth Malaysian to win an Olympic medal. He won his first silver medal in 2008, also the first time a Malaysian had reached the finals in the men's singles event. This achievement earned him the title Datuk, and led to then Malaysian Prime Minister Najib Razak describing him as a national hero. He repeated the achievement twice more in 2012 and 2016, thus making him the most successful Malaysian Olympian in history.
On 13 June 2019, Lee announced his retirement after struggling to return to full fitness following a nose cancer diagnosis. He was appointed as Malaysia's chef de mission for the 2020 Summer Olympics, but skipped the event due to his health concerns. He retained his role, albeit serving it virtually.
