Chi Alpha Delta (ΧΑΔ) (also XAD or Chis) is the oldest Asian-American cultural interest sorority in the United States.

Chis are one of the three Asian-American interest sororities and/or fraternities at UCLA, with the others being Theta Kappa Phi, and Omega Sigma Tau.

[3] The 14 Japanese-American students were rejected from a Panhellenic Greek sorority, so they decided to form one for Japanese women and those of other Asian descents.

[2] These women created Chis because they felt the need for "a same-sex, same-race organization in order to feel at home in the university.

"[3] Throughout the years Chis have accepted women of all Asian ethnicities into its sisterhood in hopes that its original purpose would not be forgotten but passed on from one generation to the next.
