Sadistic Mika Band (サディスティック・ミカ・バンド) was a Japanese rock group formed in 1972. Its name is a parody of the "Plastic Ono Band". Produced by Masatoshi Hashiba on Toshiba-EMI Records (now EMI Music Japan), the band was led by the then husband and wife team of guitarist Kazuhiko Katō, and his wife, singer Mika Fukui [ja]. The word "sadistic" is reported to be inspired by her insensitive sense of humour.
In 2003, HMV Japan ranked the band at No. 94 on their list of the "Top 100 Japanese Pops Artists". In September 2007, Rolling Stone Japan rated their 1974 album Black Ship at No. 9 on its list of the "100 Greatest Japanese Rock Albums of All Time".
