A new classification system for pulsars is proposed whereby 373 sample pulsars are divided into four natural groups by three gaps in the p vs p(dot) diagram. The validity of this classification is supported by a stepwise discriminant analysis. The first three classes correspond to the evolutionary stages based on the magnetic-decay model, and the fourth consists of millisecond pulsars which have gone through the accreting process in binary systems.
