We briefly report pressure dependence of electrical resistivity in fluorine-free, oxygen- deficient, NdFeAsO 1- y (1- y = 0.85, 0.8, and 0.6, nominal compositions) under hydrostatic high pressure up to 18 GPa. Superconducting temperatures, T C decrease in every composition by applying pressure. In NdFeAsO 0.85 , which shows no superconductivity at ambient pressure, steep drop of resistivity appears at around 20 K above 5 GPa as resistivity anomaly at around 150 K is suppressed by applying pressure.
