Wife to be Sacrificed (生贄夫人, Ikenie Fujin^?) (1974) is a Japanese soft-core pornographic S/M film starring Naomi Tani and directed by Masaru Konuma. The film was produced by Nikkatsu studios as part of their Roman Porno series.

In 1971, with theatrical audiences lost to television, Nikkatsu, Japan's oldest major film studio, had entered the soft-core pornography genre, previously dominated by independent pink film studios, in an effort to avoid bankruptcy. This move had proven highly successful for the studio for three years, but 1974 had been another difficult year for the studio. For years Nikkatsu had been trying to recruit the "Queen of Pink," Naomi Tani, into their Roman Porno series, but because Nikkatsu had been reluctant to enter the S&M genre, which was Tani's specialty, she had refused. When Nikkatsu finally consented to Tani's request to star her in a film based on Oniroku Dan's S&M novel Flower and Snake, the film—Flower and Snake (1974), directed by Masaru Konuma—became one of the studio's first successes of the year. The studio followed this first successful venture into the S&M genre with Wife to be Sacrificed, another starring role for Tani, again directed by Konuma. Because Oniroku Dan had objected to Konuma's handling of Flower and Snake, he was not involved in the making of Wife to be Sacrificed, though he later gave Nikkatsu exclusive rights to the filming of his novels. The resulting film is generally credited with firmly establishing the string of S&M films which helped sustain the company throughout the 1970s and 1980s. It became Nikkatsu's biggest hit of 1974, and remains one of their top five successes of all time. It also established Naomi Tani as the new Nikkatsu Roman Porno queen, and the first of their SM Queens.
