Reiko Oshida (大信田礼子) is a Japanese actress and singer. Oshida's career started after winning the 1966 International Teen Princess pageant (held in Chicago, Illinois). This led to a role in the Daiei Studios film School for Thieves (Kigeki: dôrobô gakkô, 1968). She subsequently appeared in all four of Toei Company's Delinquent Girl Boss films.
Unusually for a pink film actress, Oshida did not appear nude in any of her films. After the pink film's heyday of the 1970s passed, Oshida continued to appear in other roles. Her most recent appearance was in the 2005 film Satoru: Fourteen (Shonen to hoshi to jitensha).
In the 1970s, Oshida was a J-pop singer.
