Wong Weng Siu (Chinese: 黄婉秀;^[a] pinyin: Huáng Wǎnxìu; c. 1939 – 27 July 1973), more commonly known as Mimi Wong, was a Singaporean bar hostess who became the first woman to be sentenced to death and executed for murder in Singapore since its independence. Wong was alleged to have murdered Ayako Watanabe, the wife of her Japanese lover Hiroshi Watanabe, on 6 January 1970. Wong was not alone in this crime; her former husband and sweeper Sim Woh Kum had also helped Wong to restrain the victim while Wong repeatedly stabbed the woman to death.

The act was witnessed by Watanabe's eldest daughter Chieko (then aged 9), who testified against the couple in their 26-day trial. Wong's defence of diminished responsibility was rejected by the High Court, which found both herself and Sim guilty of Watanabe's murder and sentenced them to death, which also made them the first couple to be subjected to capital punishment in Singapore since its independence in 1965. Both were executed on 27 July 1973.
