The Junior Heavyweight Championship is exclusively for wrestlers 205 lbs. and under.
WLW created its first weight-exclusive title by hosting an eight-man tournament that spanned six months. The original final was a no contest in May 2016. The weight limit was 220 lbs. until August 2020.
Following WLW’s admittance as a National Wrestling Alliance territory on November 2, 2024, “NWA” was added to the title’s name.
