A fuel cell vehicle includes fuel tanks, a first support mechanism, and a restricting member. The fuel tanks are disposed in a vehicle width direction to hare longitudinal directions along a vehicle longitudinal direction. The fuel tanks include first and second fuel tanks. The first fuel tank is provided on an outer side in the vehicle width direction. The second fuel tank is adjacent to the first fuel tank. The second fuel tank has an axial center positioned higher than an axial center of the first fuel tank. In a case where a collision load acts from outside in the vehicle width direction, the first support mechanism supports the fuel tank while allowing the first fuel tank to move toward a lower side of the second fuel tank. The restricting member is provided above the second fuel tank and restricts an upward movement range of the second fuel tank.
