The Scroll and Key Society is a secret society that was established by John Addison Porter at Yale University in 1842. It rivals Skull and Bones and is one of several senior secret societies at Yale.

Founding Keysmen included Theodore Runyon (1842), later governor of New Jersey, Isaac Hiester (1842), a distinguished US congressman, and Leonard Case (1842), founder of Case Western Reserve University.

Each year, the Society's senior members choose fifteen members of the junior class at Yale to succeed them.

Tax records show that its endowment is several million dollars more than that of Skull and Bones.

Prominent members include three US secretaries of state, US supreme court justices, industrialists and financiers, US presidential candidates, Nobel laureates, and famous songwriters, writers, and movie makers:
