It is an object of the present invention to provide a pneumatic tire with improved on-snow performance, such as on-snow braking performance, on-snow traction performance, on-snow turning performance, and the like. A pneumatic tire according to the present invention includes, in at least a portion of the tread surface located between both tread ends, one or more main grooves extending in the tire circumferential direction, and a plurality of lateral grooves extending in the tire width direction between the main grooves and/or between the main groove and the tread end, the main grooves and the lateral grooves defining a block row formed by a plurality of blocks, at least one sipe being disposed in each block. Each block has formed therein a first cutaway groove with one end opening into a lateral groove located on one side of the block in the tire circumferential direction and the other end terminating within the block, a second cutaway groove with one end opening into a lateral groove located on the other side of the block in the tire circumferential direction and the other end terminating within the block, and a connecting narrow groove having a groove width narrower than that of the first cutaway groove and the second cutaway groove and connecting the first cutaway groove and the second cutaway groove.
