Our Facilities

The Oregon National Primate Research Center (ONPRC) is located on approximately 165 acres of land just west of Portland, Oregon, within the Hillsboro city limits. In addition to a variety of nonhuman primate housing, the Center maintains dedicated behavioral, clinical medicine, pathology and surgical facilities and services.

The majority of the ONPRC's nonhuman primates (NHPs) live in group enclosures: sheltered facilities with temperature-controlled indoor portions connected to outdoor runs, one-acre, grassy, outdoor corrals enriched with play equipment or indoor group housing. The remaining NHPs are housed in appropriate caging as required by federal regulations and guidelines. Every attempt is made to house animals in pairs or groups whenever possible, and thus nearly all caged animals are socially housed. To ensure compatibility and psychological well-being, all NHPs participate in ONPRC's behavioral management program (see Behavioral Services).
