We discovered that under pressure SnO with ?-PbO structure, the same structure as in many Fe-based superconductors, e.g., ?-FeSe, undergoes a transition to a superconducting state for p?6 GPa with a maximum Tc of 1.4 K at p=9.3 GPa. The pressure dependence of Tc reveals a domelike shape and superconductivity disappears for p?16 GPa. It is further shown from band structure calculations that SnO under pressure exhibits a Fermi surface topology similar to that reported for some Fe-based superconductors and that the nesting between the hole and electron pockets correlates with the change of Tc as a function of pressure.
