List of Alpha Omicron Pi chapters

A single date shown means this is the year that chapter was founded. Where two dates are shown, hyphenated, for example "1983-1993", this indicates the active dates of a chapter that has been subsequently closed. Where three dates are shown, for example "1934-1969/ 1989", this means the chapter was active between 1934 and 1969, closed, but was then re-chartered in 1989, with a continuing active presence today. In the case of four dates, "1959-1981 / 1989-1996", the chapter began in 1959, closed in 1981, reopened in 1989 and closed again in 1996.

Except where otherwise noted, chapter names, schools and dates are from the international sorority's website.
