The Clark C. Griffith Collegiate Baseball League (CGL) was a collegiate summer baseball league, with teams located in the Washington, D.C. metropolitan area. All league players had to be enrolled at a National Collegiate Athletic Association (NCAA) school, have at least one year of NCAA eligibility remaining and be amateurs by NCAA rules. The CGL was a charter member of the All-American Amateur Baseball Association and was designated a Premier League by the National Baseball Congress. The league had five teams in 2009 but suspended play for the 2010 season and does not appear to have been operational since.
