The present invention relates to a positive electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same. The positive electrode includes: a current collector; and a positive electrode active material positioned on at least one surface of the active material layer current collector. The positive electrode active material layer includes a small particle size active material having an average particle diameter D50 of 2 μm to 4 μm and a first coating layer positioned at a surface thereof, and a large particle size active material having an average particle diameter D50 of 17 μm to 21 μm and a second coating layer positioned at the surface thereof.
