The Harvard Physics Department has a large and very active undergraduate program, graduating 50-60 majors (concentrators) a year (including those in the Chemistry and Physics concentration, also administered by the department). The hallmark of the undergraduate program is flexibility, as 40-50 percent of Harvard physics graduates go to graduate school in physics or a closely related field; the rest pursue a wide range of careers including medical school, law school or business school as well as immediate employment. 25 percent of concentrators are women; 5 percent black, 20 percent Asian, and 6 percent Latino.

Physics is offered as both a concentration and a secondary field.
