The WWWA World Single Championship (WWWA世界シングル王座, WWWA sekai shinguru ōza) was the top singles women's professional wrestling championship in All Japan Women's Pro-Wrestling (AJW) from 1970 until it closed in 2005. It was also known in Pro Wrestling Illustrated and other London Publishing wrestling magazines as the All-Japan Women's International Championship. The title was descended from the original Women's World Championship, which Mildred Burke won in 1937.
