Alpha Delta Pi is an international collegiate sorority founded at Wesleyan College.[1] Following is a list of Alpha Delta Pi chapters.[2][1] Active chapters are indicated in bold. Inactive chapters and institutions are in italics.
^This chapter originated as the Adelphean Society (local) in 1851. It renamed itself as Alpha chapter of Alpha Delta Pi in 1905, on the eve of national expansion.
^In an August 1912 report published in the Adelphean, Ms. Newell Mason, a faculty member at Wesleyan and the Historian for Alpha Delta Pi, noted that "College authorities are violently opposed to sororities." A ten-year battle to remain was fought by several NPC organizations but lost in 1917 when the last members of the four sororities on campus, Alpha Delta Pi, Phi Mu, Zeta Tau Alpha and Delta Delta Delta, graduated. Since then, Greeks have not been allowed to re-establish on the campus.
^Chapter formed from Delta Delta Sigma (local), established in 1901.
^The 1930 History notes that faculty opposed fraternities, so Gamma became inactive in 1910.
^Chapter formed from Alpha Nu Sigma (local), established in 1908. The 1930 History notes that faculty opposition to fraternities led to the closure of the chapter in 1919 and the transfer of many of its members to Howard College (now Samford University).
^Chapter formed from Alpha Beta Tau (local), established in 1904.
^Chapter formed from the Cryterian Club (local), established in 1914.

^Chapter formed from Alpha Mu (local), established in 1914.

^The 1930 History notes that this charter had been transferred (~Moved) to Howard College. Many of the chapter's Judson members transferred to Howard College, bringing the charter with the "adroit approval" of the 1919 Convention. The transfer was prompted by the opposition of Judson College faculty to fraternities and the chapter's closure in 1919. Judson eventually closed in 2021.

^The 1930 History's section on Alpha Zeta chapter doesn't list a specific date of installation, but on p.366 in the province roll, it says installation took place on October 12 of 1916. Thus, it is slightly out of order among other chapters. This is perhaps because several members had entered the campus as transfers from other schools.
