PROBLEM TO BE SOLVED: To obtain a lubricating oil composition having a low viscosity, a low temperature dependence of viscosity, an excellent oil film formation and a long fatigue life. SOLUTION: The lubricating oil composition comprises a lubricant base oil having a kinematic viscosity at 100°C of 1-5 mm<SP>2</SP>/s and at least one selected from an olefin copolymer (OCP) and a poly-α-olefin (PAO) having a kinematic viscosity at 100°C of 20-2,000 mm<SP>2</SP>/s and has a kinematic viscosity at 100°C of≤8.0 mm<SP>2</SP>/s and a viscosity index of≥155.
