Abstract ： Quark--hadron duality of three proton spin structure functions g1 , g2 and gT are discussed simultaneously. It is found that the onsets of the quark--hadron dualities of g1 p , g2 p and gT p are similar and they are expected to be at about Q2 ～ 2GeV2 . In addition, our results show that the elastic peak remarkably breaks local quark--hadron duality.
