Boxing magazine The Ring began naming the top 10 pound for pound boxers in 1989. The first #1 pound for pound fighter was heavyweight champion Mike Tyson. To reduce the number of tables, a table is only added if there are changes in the rankings. For WBA titles, only titles in the primary champion lineage are listed.
