The International Lightweight Tag Team Championship was a professional wrestling tag team championship in Japanese promotion Pro Wrestling Zero1, contested exclusively among junior heavyweight wrestlers. It was created as the NWA International Lightweight Tag Team Championship on December 26, 2003 when Ikuto Hidaka and Dick Togo defeated Naohiro Hoshikawa and Tatsuhito Takaiwa in a tournament final. This was during a time when Zero1 was a member of the National Wrestling Alliance (NWA); since Zero1 departed the NWA in late 2004, NWA did not recognize or sanction it, though it retained the NWA initials. The NWA began sanctioning the title again when Zero1 rejoined the NWA in 2011. Following Zero1's departure fron the NWA that same year, NWA ceased sanctioning the title and the NWA initials were dropped. The championship was retired on December 25, 2020. During its existence it was one of two tag team titles in Zero1, along with the NWA Intercontinental Tag Team Championship, a championship typically contested among heavyweights. There were a total of 39 recognized individual champions and 28 recognized teams, who had a combined 31 official reigns.

Pro Wrestling Zero1 is a Japanese professional wrestling promotion founded in 2001.
