Welcome to Mundelein High School
Welcome to Mundelein High School! We are very excited that you will be joining the MHS family. We are looking forward to assisting your student in making the important transition from middle school to high school. On Thursday, November 12, 2026, we are hosting our Class of 2031 Incoming Freshmen Night at Mundelein High School for both families and students. The program will include an overview of our academic programs, course placements, information on the day-in-the-life of a ninth grader, and extracurricular opportunities at MHS.
