Inoue Akiko

 is a former Japanese idol and a former member of the idol group All Nighters and its sub-unit Oazuke Sisters.

She first appeared on All Night Fuji in 1983 and quickly grew in popularity. She was added to the Oazuke Sisters sub-unit in May 1984 and began her singing career. In September 1984, she dropped out of college, which was a violation of the terms and conditions of being in All Nighters. Therefore, she was forced to leave both All Nighters and All Night Fuji, effectively breaking up Oazuke Sisters.

After leaving All Night Fuji, she occasionally returned as a guest host, and retired from the entertainment industry shortly after that. As of 2014, she lives in Australia.
