A lubricating oil composition for a continuously variable transmission contains at a specific content: (A) a mineral oil or PAO having a sulfur content of 0.03 mass % or less and a kinematic viscosity at 100 degrees C. from 1.5 mm2/s to 3 mm2/s; (B) a mineral oil or PAO having a sulfur content of 0.03 mass % or less and a kinematic viscosity at 100 degrees C. from 5.5 mm2/s to 8 mm2/s; (C) PAO having a kinematic viscosity at 100 degrees C. from 30 mm2/s to 400 mm2/s; and (D) a polymethacrylate having a mass average molecular weight of 10000 to 40000, in which the total content of the components (C) and (D) is 19 mass % or more and the lubricating oil composition has a kinematic viscosity at 100 degrees C. from 5.5 mm2/s to 6.5 mm2/s and a kinematic viscosity at −20 degrees C. of 680 mm2/s or less.
