The TCU Student Government Association represents the collective voice of the student body while encompassing the spirit of the TCU community through service, programming, and legislation. SGA achieves this mission by collecting student feedback on ideas and initiatives; supporting student programming on campus; advocating to key constituents on behalf of student ideas and initiatives; and allocating funds to support student projects and organizations.

TCU SGA is comprised of three main branches – the Frog Aides freshman leadership program; the House of Student Representatives; and the Executive branch (often called Cabinet).
