Suzuki-gun was a villainous professional wrestling stable primarily appearing in the New Japan Pro-Wrestling (NJPW) promotion, and making occasional appearances in All Elite Wrestling (AEW). The group was founded in December 2010 by IWGP Heavyweight Champion Satoshi Kojima as Kojima-gun , but the members of the stable turned on Kojima and appointed Minoru Suzuki as their new leader in May 2011. Suzuki-gun added several new members, such as Davey Boy Smith Jr. and Lance Archer, known collectively as the Killer Elite Squad (K.E.S.), who are three-time IWGP Tag Team Champions and two-time NWA World Tag Team Champions as part of the stable. Other accomplishments attained by the stable include Suzuki and Archer winning the 2011 G1 Tag League and founding members Taichi and Taka Michinoku becoming one-time IWGP Junior Heavyweight Tag Team Champions. As the leader of Suzuki-gun, Suzuki became one of NJPW's top wrestlers and has challenged for the IWGP Heavyweight Championship on multiple occasions.
