In this study, we used teleseismic data which was recorded by 5 stations (DHR, GHG, KOM, LIN and VIS) of the Kermanshah Seismic Network from 2003 to 2007 with Mb?5.5 and epicentral distances from 30° to 95°. The crustal structure beneath these stations was determined by the modeling of the P receiver functions. The main phases, which were observed in our final P receiver functions, are Moho conversions, their multiples in the crust, and conversions at the base of the sediments. We obtained a 2-layer model for the crust of the Kermanshah Region. The crust beneath this region is approximately 42 km thick and consists of a 9 to 18 km thick sedimentary layer overlying a 24 to 35 km thick layer. The average shear wave velocity was estimated to be 3.69 kms-1 in the crust and reaches to 4.80 kms-1 under Moho and those obtained from other geophysical studies.
