Sigma Omicron Pi (ΣΟΠ) is an Asian American interest sorority. Founded in 1930 at San Francisco State University, the college social organization has active chapters on twelve campuses in the United States. The stated objective of the sorority is to "further the awareness of women in Asian culture" and "to promote unity, lifelong friendships, leadership, and community service".[1]


In 1930, ten Asian American women came together on the campus of San Francisco State University to form a sorority for women who were interested in teaching.[2][3] They adopted the Greek letters ΣΟΠ or Sigma Omicron Pi to represent "Sisters of Pedagogy".[3] It was the first Chinese sorority on that campus.[2] Elizabeth Ling-so Hall was a founder and the sorority's first president.[2]

Sigma Omicron Pi expanded to the University of California, Berkeley campus in 1936.[4][5] The sorority became active in the Asian community.[3] Annually, they held a fashion show to raise scholarship money with the UC Chinese Alumni Association.[2]

However, both chapters were forced to become inactive during World War II.[3] Sigma Omicron Pi was revived at the University of California, Berkeley in 1946.[3] The educational focus fell away, changing to providing fellowship, philanthropy, and cultural awareness for and among Asian American women of many Asian backgrounds.[3]

In 1994, the sorority created an Inter-Chapter Council with six elected officers to help unite the various chapters.[6]


The sororities colors are green and gold.[7] Its flower is the daisy and its jewel is the pearl.[7][8]
