Carnegie Mellon University

This year, thousands of Tartans gathered on campus for Reunion Weekend at Spring Carnival 2023. With beautiful Pittsburgh weather, CMU alumni enjoyed reunion events, watching two days of Buggy, walking through Booths, running the second annual Spring Carnival 5K, connecting with friends, engaging with current students and so much more. Check out recordings and more photos of some of our favorite moments on the Spring Carnival highlights page.
