The school was built in 1972 as a second high school for the city, when the Oshkosh West High School, formerly known as Oshkosh High School, facilities became too small to support the growing number for students. The school first opened as an open-concept school, with modular walls between classrooms, and multiple classes taking place in one room at the same time. After the 70s, the school began to shift toward a traditional layout, adding in permanent walls and separating many of the large classrooms.

Oshkosh North offers 15 unique sports. Sports offered include baseball, basketball, cross country, dance team, football, golf, gymnastics, hockey, soccer, softball, swimming and diving, tennis, track, volleyball, and wrestling, all of which participate in the Fox Valley Association.
