Datuk Lee Chong Wei (simplified Chinese: 李宗伟; traditional Chinese: 李宗偉; pinyin: Lǐ Zōngwěi; born October 21, 1982 in Georgetown, Penang) is a professional badminton player from Malaysia who resides in Bukit Mertajam. Lee won the silver medal in the 2008 Olympic Games, thus becoming the first Malaysian to reach the final of the men's singles event and ending Malaysia's Olympic medal drought since the 1996 Games. This achievement also earned him the title Datuk, and a description by Malaysian Prime Minister Najib Tun Razak as a national hero.

As a singles player, Lee was ranked first worldwide on August 21, 2008. He is the third Malaysian men's singles shuttler after Rashid Sidek and Roslin Hashim to achieve such a ranking (since official rankings were first kept in the 1980s), and is the only Malaysian shuttler to hold the ranking for more than two weeks.

Despite his number 1 status since 2008, Lee is still searching for his first Olympic Games, World Championship and Asian Games titles.
