Rutgers–Princeton Cannon War

The Rutgers–Princeton Cannon War refers to a series of incidents involving two Revolutionary War cannons and a rivalry between Princeton University in Princeton, New Jersey, and Rutgers University in New Brunswick, New Jersey. The term "cannon war" was used in this context as early as 1875.

"Big Cannon" is located behind Princeton's Nassau Hall in the center of the quadrangle there, called Cannon Green. Buried vertically since 1840, only part of the cannon remains visible. "Little Cannon" is buried near the front of Whig Hall, approximately 125 feet (38 m) from Big Cannon, in a similar manner. Big Cannon is sometimes painted red by Rutgers students, particularly in the week leading to Rutgers commencement as well as on other notable Rutgers dates.
