Mark Chung (b. June 18, 1970 in Toronto, Ontario) is an American soccer player, who currently plays left midfield for the Colorado Rapids of Major League Soccer.

Before joining MLS, Chung played college soccer for the University of South Florida.

Chung was drafted sixth overall by the Kansas City Wiz in the MLS Inaugural Draft, and finished tied for 15th in the league in points in 1996 with eight goals and nine assists. Chung would be a mainstay at Kansas City for the next two years, was named to his first MLS Best XI in 1997, and would lead all of MLS in games played at the end of its first three seasons, with 97. After 1998, Kansas City traded Chung to the MetroStars, with Mike Ammann in exchange for Tony Meola and Alexi Lalas. He would play with the MetroStars for the next three seasons, but was greatly underused by Metro coach Octavio Zambrano. Chung called the role he played with the Metros an "idiot left wing". He was traded again before the 2002 season, this time to the Colorado Rapids in exchange for a draft pick. Chung has been very successful with the Rapids, making MLS Best XI's in both 2002 and 2003.

Despite a significant amount of success in MLS, Chung has never had a significant role in the United States mens national soccer team. Chung made his first appearance April 4, 1992 against China, but has in total made only 24 appearances, and scored only two goals.

In 1995, Chung played with the San Diego Grizzlies of the CISL, being named the league's Rookie of the Year.
