List of Alpha Chi Omega chapters

Alpha Chi Omega is a collegiate women's fraternity established at DePauw University in 1885.^[1] When naming its chapters, after the first series, the new series drop one or more corresponding letter sets from the list of available names in this manner: In the "Alpha Alpha" series, there is no Alpha Alpha chapter; the name is unused. In the "Beta Alpha" series, there is neither a Beta Alpha chapter nor a Beta Beta chapter, and so on. Thus the list of available names shrinks by one more potential name each time a new series is cycled. The one exception to this is the assignation of Iota Alpha chapter, designated for alumnae initiates, used nationally.^[2]
