Provided are a separator for a rechargeable lithium battery and a rechargeable lithium battery including the same. The separator for a rechargeable lithium battery comprises: a base material; and a heat resistant multi-aperture layer positioned on at least one surface of the base material and including an imide-based co-polymer. The imide-based co-polymer includes a first repetition unit shown as formula 1 and a second repetition unit shown as formula 2. (In formulas 1 and 2, L^1, L^2, Q^1, Q^2, R, R′, a, a′, m and n are as defined in the specification) Therefore, the separator for a rechargeable lithium battery can have excellent heat resistance, excellent solubility of an organic solvent when a separator is formed, and excellent solvent resistance, and the rechargeable lithium battery can have excellent stability and performance.
