How many students does Harvard have enrolled right now?

Harvard University’s total enrollment as of the 2025 academic year is about 25,000 students across all its schools and programs. This figure includes both undergraduate and graduate students.

Harvard College, which is the undergraduate division, is significantly smaller compared to the entire university. The undergraduate population is around 7,000 students, give or take a few hundred depending on the year and a slight increase in recent classes. This means that the majority of Harvard’s students are in graduate or professional programs—these include the Graduate School of Arts and Sciences, Harvard Business School, Harvard Law School, Harvard Medical School, and several others. Across these graduate and professional programs, there are roughly 18,000 students.

So yes, you’re right: the College is much smaller than the university as a whole. For example, someone I know who attended Harvard said the undergrad community does feel tight-knit, while the grad students bring a more diverse, city-like feel to the broader campus. You’ll also notice that undergrads tend to spend most of their time in Harvard Yard and nearby houses, whereas grad students are spread out over the Cambridge and Boston campuses, often with their own buildings and routines.

If you’re deciding between schools, keep in mind that a campus with a smaller undergrad population like Harvard’s often offers a more closely connected student culture, with easy access to professors and resources. In contrast, the full university is bustling and has tons of research, events, and opportunities because of the grad student population.

You can always check Harvard’s 'Common Data Set' or admissions statistics pages for up-to-date figures, but the 7,000 undergraduates versus 18,000 graduate students split is a solid estimate for the current year.
