Tan Boon Heong (Chinese: 陈文宏; pinyin: Chén Wénhóng; Pe̍h-ōe-jī: Tân Bûn-hông, born 18 September 1987) is a former World No.1 Malaysian professional badminton player in the men's doubles event.

Nearing the Doha Asian Games in 2006, Rexy Mainaky (the Malaysian doubles coach) decided to split them up and partner Tan Boon Heong with Koo Kien Keat instead.

[2] This move, nevertheless, proved to be spot-on as this pair went on to become the Asian Games champion, winning the gold medal in their maiden outing by defeating the then Chinese world champions, Cai Yun and Fu Haifeng, in the quarterfinals, Indonesia's Markis Kido and Hendra Setiawan in the semifinals, and finally Luluk Hadiyanto and Alvent Yulianto, also from Indonesia, in the finals.

They won their first All England Open after beating Chinese pair, Cai Yun and Fu Haifeng in straight games.

At the 2010 BWF World Championships, Tan and partner Koo Kien Keat launched themselves into the semifinals after beating Korean rivals Lee Yong-dae and Jung Jae-sung.

Tan Boon Heong and Koo Kien Keat were the first Malaysian pair to enter a World Championships final in 13 years.

At the 2011 All England Open, Tan and Koo defeated 2008 Olympic champions Markis Kido and Hendra Setiawan in the quarterfinals.

Tan competed at the 2012 Olympics with Koo Kien Keat, reaching the semi-finals, and losing 0–2 in the bronze medal match to the Koreans.

[1] Tan and Koo suffered a lot of early round exits in 2013 and a three-year major title drought but they managed to remain in the top 5 of the world ranking.

Their last match together was in the third round where they lost to Chinese Taipei pair Lee Sheng-mu and Tsai Chia-hsin with a score of 19–21 in the deciding game.
