NBA Fanbases: Ranking NBA Fanbases by Attendance

5. Miami Heat (Average Attendance; 19,606)

While the Miami Heat fans usually don’t show up in their seat until just before the start of the fourth quarter, they still fill out the American Airlines Arena most nights.

The attendance is also likely higher this year due to it being Dwyane Wade’s last season in the NBA. Wade is the most important sports figure in the history of Miami and his fans are showing up more to pay respect to the legendary player.
