Johan Christian Drejer (born 8 December 1982) is a retired Danish professional basketball player who in March 2008 was released from his contract with Virtus Roma[1] 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.

This pick was not without controversy as some had been questioning his character[3] because he had quit the Florida Gators basketball team halfway through the previous season.

In his first year of college basketball, Drejer had an injury in his left foot which kept him sidelined for most of the season.

In 2007–08 he had surgery twice but never fully recovered; in March 2008 he was released from his contract by Virtus Roma and on 11 March the Basketball Federation of Denmark (Danmarks Basketball-Forbund) sent out a press release announcing Drejer's retirement.
