List of Chi Omega chapters

This is the list of Chi Omega chapters. Chi Omega's first series chapters (single-letter) are named for 24 of the Greek letters and assigned in an order customized to Chi Omega, approximating a reverse alphabetical order. The Omega chapter is reserved as a memorial designation; subsequent chapters have likewise not been assigned using the letter Omega in their names. Each subsequent series, (Alpha Alpha series, Alpha Beta series, where the second letter marks the name of the series) follow generally that same naming convention established with the first series, thus beginning with a Psi chapter and naming its chapters through Alpha. For purposes of this table, where a single prospective chapter name went unused in a series, it is shown in its assumed place within that series, and marked as unassigned. The Alpha Epsilon series was only partly used: this occurring in the early 1950s, with 17 of those names unassigned (including Omega). The Alpha Eta series was not used, with all of its 24 names unassigned (including Omega). The Alpha Iota series was not used, likewise with all 24 names unassigned (including Omega). The most recent chapter names assigned have been in the Alpha Mu series.

Since Chi Omega's founding, eight chapter names have been reassigned, with the last of these occurring in 1943.
