To ensure performance on snow and wet performance while suppressing a decrease in performance on ice, a pneumatic tire (1) includes circumferential grooves (30) extending in a tire circumferential direction, lug grooves (40) extending in a tire width direction, land portions (20) defined by the circumferential grooves (30) and the lug grooves (40), and a circumferential narrow groove (50) that extends in the tire circumferential direction and is disposed in the land portion (20). The at least one circumferential groove (30) among the circumferential grooves (30) that define the land portion (20) in which the circumferential narrow groove (50) is disposed having an amplitude in the tire width direction while extending in the tire circumferential direction to be formed in zigzag shape including a long portion (32) and a short portion (33) having relatively different lengths. The circumferential narrow groove (50) has one or more bent portions (51) where an extension direction changes in the land portion (20) to include a long portion (50a) and a short portion (50b) having relatively different lengths. The long portion (50a) of the circumferential narrow groove (50) has an inclination direction in the tire width direction with respect to the tire circumferential direction in a direction opposite to the long portion (32) of the circumferential groove (30).
