Berkeley Lab is a multidisciplinary national laboratory located in Berkeley, California on a hillside directly above the campus of the University of California at Berkeley. The site consists of 76 buildings located on 183 acres, which overlook both the campus and the San Francisco Bay.

The Lab, which conducts unclassified research, employs about 4,300 people, including nearly 1,000 staff scientists, 1,000 undergraduate, graduate students and postdoctoral fellows, and more than 1,500 technical and support personnel. In addition, each year the Lab hosts more than 2,000 participating guests.
