Disclosed are a thermoplastic polyolefin resin composition and a crash pad formed by using the same. The thermoplastic polyolefin resin composition comprises: 25 to 40 wt% of a fully cross-linked thermoplastic polyolefin (TPO) resin; 30 to 40 wt% of a partially cross-linked TPO resin; 1 to 10 wt% of a non-cross-linked TPO resin; 10 to 20 wt% of a polypropylene resin having the melting index (MI) of 1.5 to 2.5 g/10 minutes (230C, 2.16Kg); 10 to 20 wt% of a linear low density polyethylene resin; and 5 to 10 wt% of an inorganic filler.
