There have been over 650 events in UFC history since its debut in 1993. Of those events, the 10 atop the all-time attendance records provided memorable moments amplified by unique environments with palpable energy. The top 10 largest attendances in UFC history feature six countries: Canada (4), Australia (2), Russia (1), Sweden (1), Mexico (1), and Brazil (1). Eight of the events were pay-per-views, while two of the three most recent were UFC Fight Nights. Five of those events hit the 30,000 attendee mark.
