Rho Delta Chi (ΡΔΧ) (also known as "Rhos"), is an Asian-interest, but not Asian exclusive, sorority founded at the University of California, Riverside on January 17, 1991.

[1][2] Rho Delta Chi was established on January 17, 1991 as the first Asian American sorority at the University of California, Riverside.

The sorority was formed by fourteen women called Founding Mothers.

These letters were also chosen to symbolically infer the Latin word "Pax", which means "peace" in English.

Rho Delta Chi's national philanthropy is partnered with the American Lung Association (ALA).
