The Mid-Atlantic Athletic Conference (MAC) is an American high school athletic league composed of private schools in the Washington, D.C. area.
[1] Solely male teams participate in the conference.
As every member school is co-ed, the girls for all schools except Saint James compete in the Independent School League, or ISL.
The MAC is often considered less competitive than the WCAC and the IAC, but more competitive than the PVAC, the three other Washington-area private high school conferences.
