The invention provides an airbag device and an occupant protection device. The mounting airbag device includes an airbag that is inflated and deployed from a seat rear side to a seat front side of an upper portion of a seat for a vehicle by being supplied with gas during a collision of the vehicle. The airbag has front and rear chambers and an airbag body. The front-rear chamber has a pair of left and right front-rear extension parts which pass through the left and right sides of the head of the occupant and expand and deploy to the front side of the seat, and a connecting part which connects the front end parts of the pair of front-rear extension parts in the left-right direction of the seat. The airbag main body is supplied with gas through a communication hole located on the seat rear side of a connection portion of the front and rear chambers after inflation and deployment. The airbag main body is inflated and deployed toward the seat rear side after passing through a gap between the ceiling and the head of the vehicle from the seat rear side to the seat front side by the inflation and deployment of the front and rear chambers.
