The AJW Junior Championship was a tertiary singles title in All Japan Women's Pro-Wrestling.

The title started in 1980 and was retired in April 2005 when the promotion closed.

The prize was originally contested among wrestlers under the age of 20, but in 1993, they changed it to wrestlers with less than two years of experience in professional wrestling.

The first belt design was a brown belt that also represented the AJW Championship.

Later, the Junior Championship became a golden belt with a turquoise strap.
