Lee Dong-jun (born Daniel Sandrin; 27 January 1980) is an American-born South Korean basketball player.

[1] Lee began his basketball career playing for the University of Portland in the 1998–1999 season, appearing in eight games and scoring an average of 1 points.

[1] Lee's participation in university basketball was controversial because he was not a South Korean citizen and he had previously played in professional leagues in Europe.

[3] Philippine Olympic Committee president Monico Puentevella stated in media interviews that Sandrin had told him "he couldn’t relate with the Koreans because they hardly speak English … he felt more comfortable with our team.

In January 2013 he and elder brother Lee Seung-jun were booked on assault charges in Mapo District, leading to controversy over whether they should be permitted to play in the then-ongoing KBL All-Star Games.
