The 22-year-old actress completed two years at the prestigious Ivy League school in Rhode Island after enrolling in 2009.
She put her English degree on hold while she focused on her movie career, including finishing the final instalment of the Harry Potter franchise.
Watson then transferred to Oxford University, before taking another break from education to film The Perks of Being a Wallflower.
"Emma is planning on returning to studies in January," a representative for the actress told the Daily Mail.

"At Brown everyone does completely different things and very much chooses their own path, which is great, but it's also much more difficult, too. You're not with a group of people all the time at one time."
It was recently reported that Watson was confronted by a stalker while shooting upcoming film Noah in woodland.
