The Museum Ball is the longest-running annual event at MOR. Dedicated to raising funds for the Museum, this is one of the most festive and fun benefit events held annually. In addition, proceeds from the Dutch Auction support the Opening Doors for Montana Schoolchildren Fund allowing every Montana schoolchild to come to the Museum for free as part of an organized school group.

Guests can expect cocktails, a delicious dinner, dancing to a live band and a lively auction. The Ball is always held in February on the Saturday closest to Valentine's Day weekend. It's the perfect occasion to dress up and come and celebrate with friends at MOR.
