DePaul Blue Demons

The DePaul Blue Demons are the intercollegiate athletic teams of DePaul University, located in Chicago, in the U.S. state of Illinois. The Blue Demons participate in NCAA Division I and are a member of the Big East Conference. They were not affiliated with any circuit until it helped establish the Great Midwest Conference in 1991. It subsequently became a charter member of Conference USA from 1995 until its move to the original Big East in 2005. DePaul and the other six Catholic, non-FBS schools announced on December 15, 2012 their separation to eventually form a new conference that would carry the Big East name.

The origin of the Blue Demons nickname dates back to 1907 when the university changed its name from St. Vincent's College to its current form. At the time, the athletic teams had red uniforms with a large "D" on the front. After an announcer referred to the players as the "D-men," the moniker stuck and eventually evolved into "Demons." The "blue" was part of an attempt to distinguish the university's players from those of its now-defunct high school DePaul Academy. The former wore red with a blue "D," while the latter adopted the reverse. The official athletic colors are scarlet and royal blue.
