A fatigue monitoring apparatus includes a fatigue detecting helmet. The fatigue detecting helmet includes a cap, a first electrode, a second electrode, a fatigue computation device and a power supply. The first electrode is disposed in the cap to contact a head, thereby obtaining a first physiological information. The second electrode is positioned out of the cap to contact the head, thereby obtaining a second physiological information. The fatigue computation device and the power supply are disposed on the cap. The fatigue computation device includes a brainwave computation module and a fatigue judgment module. The brainwave computation module is electrically connected to the first and second electrodes for obtaining a brainwave information based on the first and second physiological information. The fatigue judgment module is electrically connected to the brainwave computation module for obtaining a fatigue information based on the brainwave information.
