Marie Fikáčková (9 September 1936 – 13 April 1961) was a Czechoslovak suspected serial killer, convicted for the killing of two newborn babies in Sušice in 1960.

In 1955, Fikáčková graduated from the medical school in Klatovy, and in 1957 she began working as a nurse in the obstetrics department of the hospital in Sušice.

Both newborns were females, aged 20 hours and 5 weeks, and the following autopsy found the babies had died an unnatural violent death.

The motive for the murders was never officially confirmed, but based on statements made by Fikáčková, claimed she developed temporary feelings of paedophobia (fear of children) during her menstruation periods.

[1] Fikáčková was convicted of murder, sentenced to death, and subsequently executed by hanging at Pankrác Prison in Prague on 13 April 1961.
