Fulton County Charter High School of Mathematics and Science, also known as Math/Science High and MSH, was a high school in Roswell, Georgia, United States, established in 2001 and disbanded in the spring of 2004. As typical for charter schools, it was housed in an old furniture store, the charter school was built around New York City's Bronx High School of Science model.

Only one student completed high school at MSHS, Gabriel Kassel. His degree was granted from another area high school, but all coursework was completed at the end of the Junior (third year) of the school's operation.

The building was subsequently leased and remodeled by the Atlanta Academy, a private K-8 elementary school in 2006. The Atlanta Academy remains in the facility, as of 2016.

Enrollment was open to all high school students in Fulton County.
