CommUniversity Day is a FREE, family-friendly festival-style event on Saturday, September 27th, 2025 from noon to 4 pm at Stony Brook University.

We invite you to explore all Stony Brook has to offer, including academics, research, health, wellness, sports, entertainment, and an array of culinary offerings. Check out our website to register for our free LEGO competition, our classic Teddy Bear Clinic, and for more information on our participants.

The event will be hosted on the Stony Brook University Academic Mall. In the case of inclement weather, it will take place on the same day and time inside of the Stony Brook Arena.
