Butte Central has participated in Model United Nations for 4 cnosecutive years representing such countries as Great Britian, DNRC, and many other. It is a way to immerse the students in the culture and ideologies of other countries to foster a greater world understanding.

"Montana Model United Nations hosts a mock simulation of the United Nations for over 500 Montana high school students each November, during the Monday and Tuesday before Thanksgiving. Sponsored by the College of Arts and Sciences, MMUN engages students by emphasizing international affairs in a hands-on, intensive two-day setting, allowing Montana high school students to explore their personal interests and learn about corners of the world that were often unknown before their participation in the program. The conference has been in existence for over 35 years." - Montana Model United Nations Website
