Alpha Chi Omega (ΑΧΩ, also known as A-Chi-O or Alpha Chi) is a women's fraternity founded on October 15, 1885. Currently, there are 132 chapters of Alpha Chi Omega at colleges and universities across the United States and more than 200,000 lifetime members. Alpha Chi Omega's official symbol is the three-stringed lyre. 

In the fall of 1885, Professor James Hamilton Howe, Dean of the Music School at DePauw University, invited seven young women from the school to attend a meeting for the purpose of forming a society. The seven young women chosen to attend this first meeting were Anna Allen, Olive Burnett, Bertha Deniston, Amy DuBois, Nellie Gamble, Bessie Grooms and Estelle Leonard. Their desire was to form an organization that would provide both close companionship and support to its members.

Their friend and associate, James G. Campbell, an undergraduate member of Beta Theta Pi who acted as librarian for the school of music offered a suggestion-that they form a fraternity. They believed that such a group would benefi t the students, the university, and the musical arts. Rumors of a new ladies' fraternity spread throughout the campus, but the group chose to be fully organized before making its first public appearance. A constitution and bylaws were drafted, the fraternity's symbols, colors, and motto were chosen, the first eight pledges were selected, and their badge was designed. All this was done before ALPHA CHI OMEGA was introduced to the DePauw University student body at a convocation held in Meharry Hall.

The young women met regularly in a small room in the music building. On October 23, 1885, one week after their initial founding, Alpha Chi Omega's Founders and their first pledges, adorned with scarlet and olive green ribbons, made their presence known. Although founded within the school of music, Alpha Chi Omega is now open to all undergraduate female students meeting our National Membership Criteria.
