The Blue Key (Fraternity) Brigham Young University Chapter (1932-2009) was an academic and service organization comprised of both men and women who ranked in the top of the class.

In 1925, the university petitioned the Blue Key National Honor Fraternity for the installation of a local chapter at Brigham young University (BYU). In 1932, the national organization contacted BYU with news that it could begin a chapter. Clyde Sandgren was appointed chairman of an investigation and organization committee, and ten men were appointed as officers and charter members. With a motto of "Serving, I live," the early days of the organization brought sponsorship of the Freshmen Treck, homecoming day, various hikes, and a trophy case in the library. The blue key symbol was adopted in 1936 and a chapter emblem was created in 1939 for maroon sweaters. As the organization continued, its responsibilities and projects expanded to include campus tours, sponsorship of the College Bowl, institution of the written Honor Code, beginning of Insigth: A Journal of Student Thought, and the creation of the wagon-wheel rivalry between BYU and Utah State University. In 1953, the club undertook the project of remounting the Y-Bell. Blue Key also awarded professor of the month and year awards, and carried out numerous honor banquets and formals. The organization reached its termination in 2009, and Larry Peer served as its last faculty advisor.
