Roncalli High School (Wisconsin)

Roncalli High School is a private, Catholic high school located in Manitowoc, Wisconsin, USA. It is owned by the Diocese of Green Bay. Founded in 1965 by the De La Salle Christian Brothers, Roncalli High School is named for Pope John XXIII (né Angelo Roncalli). Roncalli offers a college-prep curriculum. In 2022, the school merged with the Catholic elementary and middle schools, becoming known as Roncalli Catholic Schools.

The school's mascot is the Jets. A Fine Arts Center for the visual and performing arts is the newest addition. The Zimmer Auditorium hosts four dramatic productions and six instrumental and choral concerts each year.

Roncalli's educational values are inspired by St. John Baptist de La Salle, St. Francis Of Assisi, St. Edith Stein, and Pope John XXIII.
