Oregon–Oregon State rivalry

American college rivalry between the University of Oregon and Oregon State University

The Oregon–Oregon State rivalry (formerly known as the Civil War) is a college rivalry between the University of Oregon and Oregon State University. The rivalry is one of the oldest in the nation, dating back to 1894 when the two universities' football teams first met. Although the college football game is the most popular rivalry, the two universities have noted rivalry games in every sport that both sponsor. There is also an academic rivalry between the schools on occasion, and competitions for community services such as blood drives take place often.

Although determining the overall series winner is a fairly recent practice, all time records for sports between the universities have been kept since play started.
