Milford Mill Academy (MMA) is a four-year public high school in Baltimore County, Maryland, United States. It is located on the west side of the county close to the Baltimore border just outside the Baltimore Beltway.

Milford Mill Academy is located on 3800 Washington Avenue in Milford Mill, Maryland. The school was named after the area, which was called Milford where a local mill was a large part of the economy. In 1992, after several years of modernization, students returned to the school after being housed at a temporary facility. The school then renamed itself Milford Mill Academy, after being named Milford Mill High School for many years. The school borders three other high schools in Baltimore County that were built due to overcrowding at Milford Mill- Pikesville High School, Woodlawn High School, and Randallstown High School.

The school originally was a junior/senior high school. The area of the county when Milford opened its doors in 1949 was mostly rural. 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.

Milford Mill Academy received a 44.2 out of a possible 90 points (49%) on the 2018-2019 Maryland State Department of Education Report Card and received a 3 out of 5 star rating, ranking in the 27th percentile among all Maryland schools.
