Cornelius "Cornell" Glen CM (born 21 October 1981 in Port of Spain) is a Trinidadian footballer who currently plays for Mohun Bagan A.C. of India's I-League.
Glen began his professional career in 1999 with Trinidadian club FUTGOF. After two years with FUTGOF, Glen moved to Portugal, where he played for Sanjoanense. After playing slightly over a season there, he returned to Trinidad and Tobago, where he joined San Juan Jabloteh. Glen dominated the league with Jabloteh, leading the club to two consecutive league championships in 2002 and 2003, while registering 12 and 26 goals in the respective seasons.
After scoring a hat trick in a CONCACAF Champions Cup game against the Chicago Fire on 17 March 2004, Glen was bought by the MetroStars of Major League Soccer. In his first season Glen made a significant impact, registering six goals and two assists as he competed for playing time on a very crowded MetroStars front line.
Glen was traded to FC Dallas after the year for a first round pick in the 2005 MLS SuperDraft, but as the club had also acquired Carlos Ruiz he could not find any playing time among Dallas's other options at striker. Glen was traded to the Columbus Crew early in the 2005 season for a future draft pick without ever suiting up for Dallas. After scoring four goals for the Crew, he was on the move again after the season, being dealt to the Colorado Rapids for Ritchie Kotschau. Glen played only one game for the Rapids—the opener of the 2006 season—before being traded to the Los Angeles Galaxy.
