Wee Tian Siak (26 April 1921 – 29 July 2004) is a two-time Olympic basketball player. He first participated in 1948 in London as part of China’s delegation and then in 1956, when Singapore was able to send a team to the Melbourne edition. He was also selected for the 1952 Helsinki Olympic Games, but the team did not take part due to a dispute between Communist and Nationalist China.
The 1.90m-tall player dubbed as “the King” often played as a forward or centre. His competitive career lasted 22 years, with the role of 1956 Seap Games team coach as his swansong.
