The Middle Atlantic Conferences (MAC) is an umbrella organization of three intercollegiate athletic conferences that competes in the NCAA's Division III. The 16 member colleges are in the Mid-Atlantic United States.
The organization is divided into two main conferences: the MAC Commonwealth and the MAC Freedom. A third conference, named the Middle Atlantic Conference (singular), draws members from both the Commonwealth and Freedom conferences and sponsors sports that only a certain set of members participate in, such as track & field and cross country.
