The Puerto Rico Department of Agriculture (Spanish: Departamento de Agricultura) is one of the few Cabinet-level government agencies explicitly created by the Constitution of Puerto Rico[1] as the Department of "Agriculture and Commerce", most of the commerce at the time of its enactment being agriculture-based.

The DAC oversees rural development work and conservation and is headed by a cabinet secretary.

[4] The purpose of DAPR is to: DAPR administers rural development, credit, and conservation programs that are designed to implement national growth policies, and it conducts scientific and technological research in all areas of agriculture.

Through its inspection and grading services, DAPR ensures standards of quality in food offered for sale.

Throughout the years, the department's name has been modified, as well as its structure, but today remains a separate structure with additional agencies and public corporations as part of the Department of Agriculture "umbrella".
