This is a list of open or public mottos and mission statements of fraternities and sororities, categorized by the organizations to which they belong. It should be noted that most of the "mottos" which follow are public mottos and, sometimes, little more than marketing slogans which may be old or new. For most college fraternities and sororities, the Greek letters which form the organization's name are initials for Greek (or other) words and/or phrases which compose a secret motto or name, revealed only to the initiated.

Phi Beta Kappa, for example, which was the first Greek-letter organization for college students, is so-named because the group's (originally secret but now public) motto is the Greek phrase "philosophia biou kubernetes", which can be translated "love of learning is the guide of life." The initials for this Greek phrase are the Greek letters Phi, Beta and Kappa, forming the name of the society. In a similar way, nearly all fraternities and sororities maintain at least one secret phrase or name which usually corresponds to the Greek letters by which the group is known. These secret mottos are revealed to initiates during the initiation ceremonies of the organization and are nearly always considered to be part of the secrets of the group which are known to initiates and which may not be revealed to the uninitiated.
