LeBaron Russell Briggs (born Salem, Massachusetts, Dec. 11, 1855, died Milwaukee, Wisconsin, 1934) was an American educator. He was appointed the first Dean of Men at Harvard University, where he also served as dean of the Faculty. He was also president of Radcliffe College and the National Collegiate Athletic Association, among other offices.
His appointment as Dean of Men was the first "student personnel" appointment — which later became the catalyst for the Student Affairs field in higher education. Briggs was responsible for advising students academically, and on personal issues.
Among his other roles as an educator, Briggs was a trustee of Middlesex School. The school's LeBaron Briggs House dormitory is named for him.
Briggs' nautical namesake, the liberty ship LeBaron Russell Briggs, was scuttled with its cargo of nerve gas on August 18, 1970, as the last installment of a project in which the United States disposed of much of its stockpile by dumping it at sea.
Briggs Hall at Cabot House, Harvard University, is named after Briggs.
