To provide a vehicle side airbag capable of ensuring initial restraint force upon a side collision.SOLUTION: A vehicle side airbag 10 is stored inside a vehicle seat 14, and is inflated and deployed on a lateral side on the vehicle width direction outside of an occupant P when supplied with gas from an inflator upon the prediction or detection of a side collision. Further, the vehicle side airbag 10 includes: an upper chamber 10B which covers the lateral side of a head part H of the occupant P in the state of being inflated and deployed; and a lower chamber 10C which covers the lateral side below the head part H of the occupant P in the state of being inflated and deployed. The upper chamber 10B is stored in the upper end part of a seat back 18 while being folded in a seat front-rear direction, and is inflated and deployed toward a space between the upper rear face of a shoulder belt 26A for restraining the upper body of the occupant P to the seat back 18, and a headrest 20.SELECTED DRAWING: Figure 1
