The University of Detroit Jesuit High School and Academy (commonly referred to as U of D Jesuit, The High, Detroit Jesuit, or U of D) was founded in 1877, and is one of two Jesuit high schools in the city of Detroit, Michigan, (Loyola High School being the other). Located in the Roman Catholic Archdiocese of Detroit, the school is rooted in the Ignatian tradition. It is an all-boys school with an academy for grades seven and eight. The school's mascot is the Cub and its teams are dubbed the Cubs. Its colors are maroon and white, though black, grey, and gold appear on team uniforms.
Approximately 500 Jesuits have taught at U of D Jesuit since its founding in 1877; in 2016 there were eight Jesuits assigned to the school. Lay faculty first joined the staff during World War I and by the school's 100th anniversary in 1977 the lay to Jesuit ratio stood at nearly 3 to 2. In 2007 the school celebrated its 130-year anniversary, making it the oldest Catholic high school in the city of Detroit. The school was highlighted by Time in its November 9, 2009 issue, as one of the last Catholic high schools remaining in the city of Detroit.
