Chairs and punches where thrown when a large fight broke out in the audience at the Centenary Pavilion in Elland Road, Beeston, on Saturday, February 18.
The Pavilion suite had been hired out for the white collar event but the main fight, between boxers Mikey Bourne and Mark Holmes, did not go ahead due to the violent scenes.
Police were called just before 10.30pm after the disorder broke out and crowds dispersed, but three people needed hospital treatment for “minor injuries”.
Leeds United, which owns the venue, has since said it will no longer host white collar boxing events.
The majority of those now charged live in Leeds, although three of the defendants are from Castleford, Pontefract and Wakefield.
All the defendants are due to appear at Leeds Magistrates' Court this morning.
