Gamma Pi Epsilon (ΓΠΕ) was the women's honor society of Jesuit colleges and universities.

When Marquette University went co-ed in 1924, there was a desire for a women's honor society alongside the all-male Alpha Sigma Nu which had been created nine years prior.

Gamma Pi Epsilon was approved in 1924 and the first chapter chartered on April 6, 1925 at Marquette University.

[3][4] Gamma Pi Epsilon collaborated with Alpha Sigma Nu, with both groups chartering new chapters on campuses at the same time.

[5][4] Gamma Pi Epsilon's motto was "Pour Gloise L'Ecole" or "For the Glory of the School".
