Mark Baena (born November 27, 1968) is an American former professional soccer player.

Baena is the highest goalscorer in the history of USL First Division, where he amassed eighty-six goals.

However, on November 27, 2001, the Timbers released Baena at his request in order to allow him to pursue business opportunities.

Baena was approached by Major League Soccer to sign a multi-year contract after each of the 1997, 1998, and 1999 seasons.

Baena again could not reach terms with the MLS after the 1998 and 1999 seasons and opted to continue his career in the USISL/A-League (USL).

Baena's only appearance was in 1999 as a second-half substitute for the San Jose Clash in an exhibition game against UNAM Pumas of the Primera División de México.

Baena was in training camp with the San Jose Earthquakes for a very short time during the 2002 pre-season, but opted to remain retired.
