The Twin City Derby Girls (TCDG) is a roller derby league based in Champaign-Urbana, Illinois. Founded in 2010, the league currently consists of three home teams, and a highly competitive Travel Team which compete against teams from other leagues.
Twin City was established at the beginning of 2010. By the end of the year, it was regularly selling out its venue - for the final bout of the season, it sold out in twelve minutes. As a result it, moved to the 1,200-seater University of Illinois Ice Arena for the 2011 season.
