The IWRG Intercontinental Lightweight Championship is a singles professional wrestling championship promoted by International Wrestling Revolution Group (IWRG) since May 2008.

Aguila Roja is the current champion, having defeated Spider Fly on October 29, 2023 at an IWRG show.

[1] The championship has only changed hands in Arena Naucalpan on IWRG promoted shows.

[b] On occasion the promotion declares a championship vacant, which means there is no champion at that point in time.

This can either be due to a storyline,[c] or real life issues such as a champion suffering an injury being unable to defend the championship,[d] or leaving the company.
