Princeton's main rival for many years has been former NCIC conference-mate Hall High School from nearby Spring Valley. The rivalry is probably the most intense when the two schools meet in football; it is uncertain as yet what impact the end of the NCIC will have on the relationship between the two schools. A more recent rivalry has developed with nearby Bureau Valley High School, which was just formed in 1995. Many heated battles have taken place between the two teams in basketball. They have met for several intense Regional and Sectional final games, however their rivalry does not extend to football because the two teams are in different conferences and different IHSA classes. Another rivalry is between Princeton and Kewanee High School. Despite the fact that the teams compete annually for a traveling trophy in football, this rivalry is much less intense than those with Hall and Bureau Valley.
