The Cagayan State University (abbreviated to CSU) is the second largest state institution of higher learning in the Cagayan Valley Region, in terms of enrollment and number of curricular program offerings. The University was established through Presidential Decree 1436, later amended by Republic Act 8292 by the integration of all publicly supported higher education institutions in the province of Cagayan. The university is composed of eight(8) campuses in the growth areas in the three congressional districts of Cagayan; the Aparri, Lal-Lo and Gonzaga campuses in the 1st District; the Piat, Lasam and Sanchez-Mira campuses in the 2nd District; and in the 3rd District, the Caritan and Carig campuses in Tuguegarao City. Each campus is headed by an Executive Officer (CEO), equivalent to the Chancellor of the University of the Philippines except in the campuses of Tuguegarao City where the University President concurrently acts as the CEO. The seat of governance of the university is at the Andrews Campus, where the central administration holds office.
