The Independent World Junior Heavyweight Championship (Japanese: インディペンデントワールド世界ジュニアヘビー級王座, Hepburn: Indipendento Wārudo Sekai Junia Hebī-kyū Ōza) is a professional wrestling championship that is being defended in various independent promotions in Japan.

On May 31, 1999, Kodo Fuyuki became the FMW commissioner and withdrew the recognition of the title following the introduction of the WEW Single Championship which he awarded to himself on September 24.

Yuhi Sano was then recognized as the first Independent World Junior Heavyweight Champion, in continuation of his FMW Junior Heavyweight Championship reign, thus starting a third lineage.

Despite FMW no longer recognizing the title, the original championship belt—still bearing the 'FMW' name—continues to be used.

In May 2010, a new belt was created when Tarzan Goto's Super FMW promotion briefly revived the FMW Independent World Junior Heavyweight Championship to crown its final champion.
