The Office of the Dean of Undergraduate Students and the four class governments (2027, 2026, 2025, and 2024) are elated to host the Orange and Black Ball: Disco Ball on Thursday, November 2, 2023 from 9:00pm to 12:00am in Dillon Gym.

The Orange and Black Ball (OBB) is a longstanding tradition that brings the Princeton University undergraduate community together. OBB is the only formal event open to all four undergraduate class years.

Adorn your glitter, sequins, and bell-bottom pants as you dance the night away under shimmering disco balls, colorful lights, and funky, retro designs. Disco attire is encouraged, but not required. This event is for Princeton University undergraduate students only.
