CUAA is an acronym for Christian Union (UNIBEN/UBTH) Alumni Association. It is statutorily made up of all graduates from the University of Benin (UNIBEN) and University of Benin Teaching Hospital (UBTH) who were members of the Christian Union campus fellowship. The constitution of the association however extends membership to spouses of members as well as other well-meaning believers who wish to identify with the aims and objectives of the association.

CUAA has undergone a few metamorphoses in her name.  It was first referred to as the Senior Friends Fellowship when a few brethren saw the need for alumni members to maintain fellowship among themselves upon graduation from the school and campus fellowship. Their coming together to have a structure led to Bro. Kingsley Akhigbe serving as her first known president from 1985 to 1989.  He was succeeded by Engr Mike Ajado who served from 1989 to 1993.  It was during his leadership that the name of the association was changed to Christian Union Alumni Association (CUAA). Then in 2005 as a result of the successful merger of the Christian Union (CU) and NIFES campus fellowships (which was consummated in 2003), the constituent alumni bodies saw the need to also merge to become Christian Union – Nigeria Fellowship of Evangelical Students (UNIBEN/UBTH) Alumni Association abbreviated as CUNAA.  However, in 2022, after NIFES opted to leave the union, the alumni association reverted back to CUAA.
