Milford Mill Academy (MMA) is a four-year public high school in Baltimore County, Maryland, United States.

The school was named after the area, which was called Milford where a local mill was a large part of the economy.

[2] In 1992, after several years of modernization, students returned to the school after being housed at a temporary facility.

In the early and mid 1950s, the school became overcrowded, forcing the county to build a separate junior high (Sudbrook; grades 7-9)and the renamed high school dropped the "Junior" from its name.

[4] Milford Mill offers 7 different magnet programs for students interested in subjects of their talent.
