The Northwestern University Dance Marathon, commonly known as NUDM, is a philanthropic dance marathon held every March at Northwestern University in Evanston, Illinois. Founded in 1975, NUDM is one of the nation's most established and largest entirely student-run philanthropies. NUDM is one of the only annual Dance Marathons in the country to continually change its primary beneficiary. NUDM has raised over $1 million for its beneficiaries each year since 2011, and involves over 1,000 students participating as dancers and committee members. Since 1997, the Evanston Community Foundation has been NUDM's secondary beneficiary.
