The present disclosure relates to the field of electronic technology, and provides an EEG processing apparatus and method and a sleep monitoring wearable device, which can reduce complexity of sleep staging. The EEG processing method comprises: obtaining EEG data to be processed (101); analyzing the EEG data to be processed to obtain a predetermined number of segments which do not overlap each other (102); obtaining a maximum value and a minimum value of a peak-to-peak value in each of the segments (103); normalizing a connection line between the maximum value and the minimum value of the peak-to-peak value in at least one of the segments to obtain upper end points and lower end points of the connection line (104); calculating statistic characteristic values of an upper sideband curve formed by the upper end points to obtain a box plot series (105); and obtaining a sleep staging result based on the box plot series (106).
