The University of the Philippines Los Baños (UPLB) is a state university located in the towns of Los Baños and Bay in the province of Laguna. It traces its roots to the UP College of Agriculture (UPCA), which was founded in 1909 by the American colonial government to promote agricultural education and research in the Philippines. UPLB was formally established in 1972 following the union of UPCA with four other Los Baños and Diliman-based UP units.
