The cell parameter of cubic iron monosilicide, epsilon -FeSi, has been determined at 25 pressures between 0 and 9 GPa by time-of-flight neutron powder diffraction, using the POLARIS diffractometer at the ISIS spallation neutron source. NaCl was used as an internal pressure standard. Fitting of the data to a third-order Birch-Murnaghan equation of state with K<sup>'</sup><sub>0</sub> fixed at a value of 4.0 gave an isothermal bulk modulus K<sub>0</sub>, of 160(1) GPa.
