An exhaust gas purification catalyst that has an excellent exhaust gas purification performance while suppressing pressure loss increases. The exhaust gas purification catalyst is provided with a substrate having a wall-flow structure and having a partition; a first catalyst layer formed, in a region of an interior part of the partition that is in contact with an entrance cell, along the extending direction of the partition from an exhaust gas inflow-side end for less than the total length Lof the partition; and a second catalyst layer formed, in a region of an interior part of the partition that is in contact with an exit cell, along the extending direction of the partition from the exhaust gas outflow-side end for less than the total length Lof the partition. The first catalyst layer and the second catalyst layer are configured to partially overlap with each other in the extending direction.
