Datuk Wira Lee Chong Wei DB PJN AMN DCSM DSPN (born 21 October 1982) is a retired Malaysian professional badminton player. As a singles player, Lee was ranked first worldwide for 349 weeks, these including a 199-week streak from 21 August 2008 to 14 June 2012. He is the fourth Malaysian player after 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 to hold the number one ranking for more than a year.
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.
