Johan Christian Drejer (born December 8, 1982) is a retired Danish professional basketball player who in March 2008 was released from his contract with Virtus Roma and is a former player of SISU Copenhagen, the Florida Gators, Winterthur FCB and Virtus Bologna.
Drejer was named the Basketligaen Player of the Year in 2002 after averaging 31.6 points and 6.4 rebounds per game.
He was also a Danish national team player.
He was drafted in the second round of the 2004 NBA draft by the New Jersey Nets with the 51st pick as the first Dane ever drafted by the NBA.
This pick was not without controversy as some had been questioning his character because he had quit the Florida Gators basketball team halfway through the previous season.
