This is a list of the 25 largest announced attendance figures in the history of American professional indoor soccer. Except for the Chicago Sting/Tampa Bay Rowdies game of Feb. 14, 1982, all of these games took place in the original Major Indoor Soccer League. (It’s not likely any game in the current league is going to crack this list. In fact, you have to go down to the 86th game on the list – the final game of the 2002 finals in the second MISL – to find a game from this century.)
Playoff games are denoted with an asterisk on the date. Documented corrections and additions are always appreciated.
