List of senior societies

Senior societies are a type of collegiate student organization that recruits juniors and seniors. Senior societies are associated with Dartmouth College, the University of Pennsylvania, and Yale University. These societies can be activity-based, identity-based, school-based (departmental or academic field), or traditional. Senior societies may be "landed", owning a building or tomb, or "non-landed".

Baird's Manual of American College Fraternities (1883), notes that Phi Beta Kappa, founded at the College of William & Mary in 1776, was the first senior society. At Dartmouth University, senior societies date back to 1783 with the founding of an organization called the Society of Social Friends. Dartmouth currently had fourteen active senior societies. Yale has more than forty active senior societies. The oldest senior society at Yale is Skull and Bones, established in 1831, followed by Scroll and Key in 1841. Other colleges have similar organizations but use different terminology. For example, there are Princeton University eating clubs and Harvard University final clubs.

Senior societies tend to be exclusive, and members pay dues to belong. Members are most often recruited by a process called "tapping". Membership in each senior society tends to be small, averaging around fifteen active members. Some senior societies are also secret societies, where the names of members are kept secret, while others are open and share their membership rolls. Other senior societies are semi-secret, keeping member's names a secret until graduation. Some senior societies also are considered honor societies.
