The CMLL Japan Women's Championship, also known as the CMLL–Lady's Ring Japan Women's Championship and the CMLL Japanese Women's Championship, is a women's professional wrestling championship, promoted by the Mexican lucha libre promotion Consejo Mundial de Lucha Libre (CMLL) and Japanese joshi puroresu promotion Lady's Ring. India Sioux is the current champion, the eleventh overall champion and her reign is the eighth since the championship was reactivated in 2020. She won by the title by defeating Hazuki at Stardom Cinderella Tournament 2026 on March 15, 2026, in Yokohama, Japan.

The championship was first introduced in 1999 as the CMLL Japan Women's Championship, when CMLL was touring Japan in hopes of expanding into the Japanese market. By 2000 CMLL ceased promoting shows regularly in Japan, loaning the CMLL Japan Women's Championship to Osaka Pro Wrestling, who kept promoting the championship until June 2001. The championship was reactivated as the CMLL Japanese Women's Championship in 2020 by CMLL and their Japan-based partner Lady's Ring, and would later also be recognized by the World Wonder Ring Stardom promotion. The inaugural and youngest champion is Chikako Shiratori at 26, while Dalys la Caribeña is the oldest at 44.
