# List of Alpha Chi Omega chapters

Alpha Chi Omega is a collegiate women's fraternity established at DePauw University in 1885. 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.
In the following list, active chapters are indicated in bold and inactive chapters are indicated in italics.
