A multifunctional helmet has a helmet and a ventilation module. The helmet has a shell with a jaw guard integrally formed at a front of the shell. A mounting slot is defined in the jaw guard. The ventilation module is mounted in the mounting slot. The ventilation module has a housing, a fan and a switch group. Switches in the switch group control the fan to draw air into the helmet or expel air out of the helmet. In addition, a lighting module is added to the helmet to provide light when required.
