Marshall Harrison Plumlee (born July 14, 1992) is an American former professional basketball player and an active-duty United States Army Ranger-Qualified officer.

[1] He was one of the top-rated basketball recruits in the class of 2011, a McDonald's All-American,[2] and is the younger brother and former high school and college teammate of both Mason and Miles Plumlee.

A native of Warsaw, Indiana, Plumlee joined his older brothers as boarding students at Christ School in Arden, North Carolina.

By his junior year, when both his brothers were playing for Duke, Plumlee averaged 8.6 points, 8.0 rebounds, and 2.6 blocks per game.

[8] Plumlee's five-player recruiting class for Duke in 2011 included Austin Rivers, Alex Murphy, Quinn Cook, and Michael Gbinije.

[10] During his final season at Duke, Plumlee served as a team captain along with Amile Jefferson and Matt Jones.

He was rushed into the city from his D-League assignment when starting center Joakim Noah was sent home due to illness.

According to Plumlee, his inspiration to serve in the military stemmed from his childhood just as his desire to play professional basketball.

[22] In May 2022, Plumlee announced that he would be entering the two-year MBA program at Harvard Business School, joining the HBS class of 2024.
