The Greenbrier Military School was a boys-only, private, military, boarding high school and Junior College, located in Lewisburg, West Virginia.

In the early 2000s, alumni of The Greenbrier Military School created a program called The Greenbrier Cadet Program where they partnered with Fork Union Military Academy.

The program honors one cadet each year that exemplifies the values held by The Greenbrier Military School and the cadet wears an honor cord which is presented at the spring parades, where Greenbrier Military School alumni are the guests of honor.

The Greenbrier Military School Alumni Association (GMSAA) directs and funds the Greenbrier Military School Leadership Scholarship, that grants scholarships to at least one graduating senior from both Greenbrier East High School and Greenbrier West High School.
